Definition & Pronunciation

IPA:/slæŋ/Phonetic Spelling:slang

Slang is very informal language used by a particular social group, age group, profession, community, or subculture. Slang words and expressions often create familiarity, humor, identity, secrecy, emphasis, or emotional impact.

Slang may be playful, affectionate, insulting, vulgar, sexual, regional, temporary, or highly specific to an online community. Its meaning can change quickly, and a term understood by one group may confuse or offend another.

In sexual and gender-related language, slang may refer to bodies, sexual acts, attraction, relationships, sexual orientation, gender identity, pleasure, or sexual reputation. Some sexual slang is neutral or humorous, while other terms are degrading, discriminatory, or unsuitable for formal communication.

Slang means informal words or phrases that people use in casual conversation.

Slang may be used to:

  • sound friendly or relaxed;
  • show membership in a group;

  • Online slang can become outdated quickly.
  • Some sexual slang is playful between consenting adults.
  • A slang word may be inappropriate in a medical appointment.
  • Understanding the context is important before using unfamiliar slang.

Slang is not automatically bad English. It is simply less formal and more dependent on social context.

Grammatical Formation and Usage

Slang is usually an uncountable noun:

  • The conversation contained a lot of slang.
  • She studies internet slang.
  • Sexual slang changes between generations.
  • Avoid excessive slang in formal reports.

To refer to individual examples, use:

  • a slang word;
  • a slang term;
  • a slang expression;
  • several slang phrases.

The adjective may appear before a noun:

  • a slang expression;
  • a slang dictionary;
  • a slang meaning;
  • slang usage.

The adjective slangy means containing a great deal of slang or sounding highly informal:

  • The dialogue was natural but slightly slangy.
  • His slangy message was unsuitable for the official email.

  • use slang;
  • understand slang;
  • modern slang;
  • internet slang;
  • youth slang;
  • regional slang;
  • sexual slang;
  • offensive slang;
  • slang for a body part;
  • become standard slang.

Slang and Colloquial Language

Colloquial language is informal language commonly used in everyday speech.

Slang is often more group-specific, fashionable, expressive, or temporary.

Compare:

  • Kids is an ordinary colloquial word for children.
  • A newly invented online term may be slang.
  • Colloquial expressions may remain common for generations.
  • Slang may become outdated within a few years or even months.

The categories overlap, and some slang eventually becomes ordinary conversational English.

Slang and Jargon

Jargon is specialized vocabulary used by people in a profession, academic field, hobby, or technical community.

Slang is informal language used mainly for social identity, humor, emphasis, or casual communication.

For example:

  • Medical professionals use technical jargon such as hypertension.
  • Friends may use slang to describe dating or attraction.
  • Jargon can be formal but difficult for outsiders to understand.
  • Slang is usually informal and may carry emotional or cultural meaning.

A word may function as both jargon and slang in different settings.

Slang and Euphemism

A euphemism is a mild or indirect expression used instead of language considered uncomfortable, embarrassing, or offensive.

Slang may be direct, humorous, vulgar, or indirect.

For example:

  • Sleep together is a euphemism for having sex.
  • A crude informal word for intercourse is sexual slang.
  • A playful nickname for genitals may be both slang and euphemistic.
  • A clinical term such as penis is neither slang nor a euphemism.

Euphemisms soften meaning, while slang mainly marks informality or group usage.

Sexual Slang

Sexual slang includes informal words and expressions related to:

Sexual slang may help people speak casually or humorously, but it can also create confusion because meanings vary.

For example, one slang term may be affectionate in a privaterelationship but insulting when directed at a stranger. Another may have different meanings in different countries or generations.

In healthcare, consent discussions, and sexual education, clear anatomical or descriptive terms are often safer than slang.

Slang, Vulgarity, and Profanity

Not all slang is vulgar, and not all profanity is slang.

Vulgar language is considered crude, indecent, or socially offensive.

Profanity includes swear words, curses, or strongly offensive expressions.

Slang may be completely harmless, such as informal terms for friends, clothing, music, or relationships.

Some sexual slang is vulgar because it directly refers to genitals or sexual acts. Other sexual slang may be mild, humorous, affectionate, or widely accepted.

Group Identity and Belonging

Slang can help people express identity and connection.

It may be associated with:

  • age groups;
  • regions;
  • professions;
  • LGBTQ+ communities;
  • ethnic or cultural groups;
  • online communities;
  • music scenes;
  • sexual subcultures.

Using shared slang may create a sense of belonging. However, outsiders should be cautious about using terms connected to another group’s identity, especially when the term has a history of insult or discrimination.

Reclaimed Slang

A reclaimed term is a formerly insulting word that some members of the targeted group begin using positively, humorously, or politically.

Reclamation may help people:

  • resist shame;
  • build solidarity;
  • weaken the insult’s power;
  • express identity;
  • create in-group humor.

However, reclamation does not make the word acceptable for everyone. A term used proudly within a community may remain offensive when used by outsiders or in a hostile tone.

Identity, relationship, history, intention, and context all matter.

Slang and Sexual Consent

Slang may cause misunderstandings during intimate communication.

A person may use a slang term for:

  • a body part;
  • a sexual act;
  • a relationship status;
  • a boundary;
  • a fantasy.

Another person may interpret the same word differently.

Clear consent requires more than assuming shared slang. Partners may need to ask:

  • “What do you mean by that?”
  • “Are you asking for this specific activity?”
  • “Is that word comfortable for you?”
  • “Do you want me to stop?”

Direct, respectful communication is especially important when a slang expression is vague or has several meanings.

Offensive and Harmful Slang

Some slang terms demean people based on:

  • gender;
  • sexual orientation;
  • gender identity;
  • sexual history;
  • disability;
  • race or ethnicity;
  • sex work;
  • body shape or anatomy.

Such words may reinforce misogyny, homophobia, transphobia, slut-shaming, or other forms of stigma.

Even when a speaker claims to be joking, the effect may still be humiliating or threatening. Repeated unwanted sexual slang in a workplace, school, or public setting may become harassment.

Slang in Formal and Educational Settings

Slang may be unsuitable in:

  • medical records;
  • academic writing;
  • legal documents;
  • workplace reports;
  • formal speeches;
  • sexual-health instructions.

However, educators and healthcare professionals may need to recognize common slang so they can understand what people mean.

A useful approach is to acknowledge the slang term and then provide the standard term:

  • “That slang word usually refers to the penis.”
  • “The clinical term for that body part is vulva.”
  • “People use that phrase differently, so let us clarify the exact activity.”

This approach improves understanding without shaming the speaker.

Connection to Sexuality

Slang is connected to sexuality because people frequently use informal words for bodies, desire, sexual acts, relationships, orientation, pleasure, and sexual reputation.

Sexual slang can make communication playful and accessible, but it may also be vague, stigmatizing, or offensive. Reclaimed terms may express identity within a community while remaining inappropriate for outsiders.

Respectful sexual communication distinguishes slang from accurate anatomical and health terminology. It considers consent, audience, cultural meaning, and the effect of language on the people being described.
