Inverted Porcupine

Slut - meaning if you inverted a porcupine, there would be a lot sticking in as opposed to sticking out - see Pin Cushion

Inverted Porcupine

When someone has more dicks inside of them then outside of them.

"Man, Pierre is so gay he's like an inverted porcupine; he's got more dicks inside than outside!"
