1.
The unnecessary and mysterious pocket covering the crotch in men's underwear, usually tighty-whiteys. Useful for holding whatever men may wish to keep close to home.
Girl 1: I tried looking for tight and sexy underwear for my boyfriend, but I couldn't find any without the manpocket!
Girl 2: I love a man who wears a manpocket.
