Sexual slang

Sexual slang is any slang term which makes reference to sex, the sexual organs, or matters closely related to them.

Introduction

In the popular jargon of many cultures, the use of sexual slang is a form of humor or euphemism that often creates controversy over its popular use. Sexual humor is seen in many circles as crude and unsophisticated, as well as insulting towards the subject it describes. Nevertheless, sexual humor has been popular since the earliest days of civilization, and crude humor is seen as having its own place in popular culture.

Sexual slang is often used by adolescent youths as a ritual of growing up. It is one way that youths often test the limits of tolerance in their society, both in their own families and in the community in general.

The popularity of various comedians who indulge in sexual slang, from George Carlin to Andrew Dice Clay, reflects the appeal of this form of speech. It is often seen as a form of taboo, where much of its appeal comes from the shock value of daring to speak "forbidden" words in public.

Body parts

For slang terms describing sexual organs and related parts of the body, see Body parts slang.

Activities

Full session of sexual activity

A group of slang terms dealing with sexual activities, borrowing terms from baseball, is in particular circulation among Americans. Details vary, but most criteria are similar.

First base - Kissing, especially "French" kissing.
Second base - Fondling or groping, especially of the breasts or genitals.
Third base - Depending on the speaker, either full nudity or a non-intercourse orgasm (especially when resulting from oral sex) EX: Dry Humping.
Home run (or "Hitting it out of the park", etc.; sometimes "Fourth Base") - Sexual intercourse.
Grand Slam - Being a player/anal sex or inducing an intense orgasm, even "shejaculation".

A common mnemonic device for the bases is "french, feel, finger, fuck."

Anal sex is sometimes also referred to as "extra innings," "the dugout," or "fifth base."
