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?
