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.

Damn it feels good to be a gangsta
A real gangsta-ass playa plays his cards right
A real gangsta-ass playa never runs his fuckin mouth
Cuz real gangsta-ass playas don't start fights
And playas always gotta high cap
Showin' all his boys how he shot em
But real gangsta-ass playas don't flex nuts
Cuz real gangsta-ass playas know they got em.
