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.

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.

The act of pulling one's scrotum (testicles included) through the opening in one's pants or shorts, thus exposing the beauty of one's gonads for all to admire. Named for the remarkable resemblance of the display to a human brain, hanging in the breeze.

hanging brain 

When your balls hang out the leg of your shorts and you are not even aware of it.

This commonly occurs when you lean back and put your legs up, while in a seated position and you're rockin short, loose-fitting bottoms, i.e., short shorts or short swim trunks.

Being stoned helps, too.

This occurs with a much higher degree of frequency in wearers of boxers than in wearers of more supportive undergarments.

Did you see that? Tom was hanging brain the whole time he was hitting on that chick! I wonder if she noticed?
