My Flashcards

Definition

An Australian English slang term for men's underwear, specifically briefs or boxer shorts.

Informal term for undergarments in general, though predominantly used for men's underwear. It can carry connotations of casualness, working-class speech, or humorous self-deprecation.

Connotations
