A term coined by sex advice columnist Dan Savage that refers to an act of love making that involves a woman with a strap-on dildo anally penetrating her male partner.

A stupid person; it refers to the lack of surface area on an individual's brain. The general thought is that the more surface area (wrinkles, creases, etc.) a brain has, the smarter the person is. Conversely, a person with a smooth brain (no wrinkles) has less surface area and would therefore be stupid.

Post Ejaculatory Guilt Syndrome, or PEGS, is a little known but widely experienced sexual dysfunction which lasts for approximately 5 minutes after the male orgasm.This can occur both after sexual intercourse and more commonly following masturbation. During this period the male in question will find himself completely unattracted to the person or subject matter concerned in the previous activity. The male may also experience emotions of disgust or dislike towards both themselves and any other people they interact with during the PEGS period.

To falsely assume something about a person. Often based on stereotypes or outward appearances. It can be used in both the positive and the negative (ie, someone is "pegged" with a characteristic they do not possess; or they are "not pegged" with a true but hidden characteristic.)

Derived from the hypothetical idea of "pinning (or pegging) a label on someone".

Australian slang, meaning to throw an object very hard and fast. Generally an object small enough to fit in one hand.
