Impenetrable bush 

A large amount of hair located around the buttocks and anal region. Some people decide not to shave this region due to the fact that it renders the individual immune to any attempts at sodomy.

Dude 1: "Yo man, I heard your homeboy just got out of the pen, did he get it up the butt at all?"
Dude 2: "Nah doggy, that mutha fucka's ass has an impenetrable bush, no one got near that shit."
