hanging brains 

When a dude pulls his hairy balls out of his zipper and attempts to walk around the bar and pick up unsuspecting chicks. The irony is that he is actually using the only brains that he has!

Brandon Abby was hanging brains at the bar last night.

hanging brains 

When a guy bends over naked and all you see is his droopy nut-sack.

I was completely into Ted until he bent over, hanging brains.

Hangin Brain

Occurs when your female partner is giving you a blowjob and then you cum in her mouth. Superbly she goes to swallow your load when you jam your cock in farther causing her to choke. This movement naturally re-routes your discharge through and out her nose creating the "Hangin Brain".

Due to Sara's superb oral efforts, I gave her a little extra. She smiled up at me with surprise exposing her new hangin brain.

Hangin Brains 

The act of exposing the scrotum out the fly hole of your pants.

It was a real blast hangin brains back in high school.
