Flex nuts. A term coined by the Geto Boys in their song "Damn it feels good to be a Gangsta"

The metaphorical act of flexing ones testicles to make them bigger than they are. however physically impossible this act is, it simply means to play tough when you feel inadequate.

Polite/slang way of saying "Fuckin Nuts".

n. the sexual act of fuckin a person in the ass (male or female will do) in a full bathtub and enjoying their underwater screams.

17. green day

One of the greatest punk bands of all time. They had 2 minor albums (1039 Smoothed Out Slappy Hours, which is a collection of the album 39 Smooth, and the EPs 1000 hours, and slappy, and kerplunk!) before they made dookie and hit it big. theyve made more hit studio albums, like insomniac, nimrod, warning, and their newest one, american idiot. theyve also produced a greatest hits album (international superhits) and a rarities album (shenanigans).

green day really is a good band, and idk why some people diss them alot. theyve got good songs, and play really well. most of u who dont like them probably have never even heard one of their songs let alone all their albums, try listenin to them b4 u make a judgement call.

Green Day made a new CD, american idiot, on september 21, 2004

when you are a fat fuck who has a double chin that looks like two hairy testicles.

first used during the ice age when ag would say to thog "chin nuts" and then have random masturbations all over the castle of doom and love.

when a girl is teabaging and bite the nuts so hard they crack

When a man farts while sitting on a nonporous (usually leather) seat and the gas expanding from his anus rapidly pushes his nuts forward, approximating the behavior of a pneumatic piston or cannon. Frequently catalyzed by the presence of tight pants and/or sweaty ass/thighs.
