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."

impentrable 

like impenetrable but tougher. so tough you cant even see the e

the memories are impentrable
and that is all for the night.

freezes my already cold mind

as death is at our doorstep

waiting to steal our innocence

but not our substance but you

are not alone in this.
