Poostank 

When you're smashing someone from behind and they then proceed to shit all over your dick with a putrid amount of diarrhea shit which fills the air around you as you inhale the glorious fumes of your girl, you feel at peace and one with nature.

I was smashing my girl from behind going in it raw and she gave me the poostank!
