When a gurl has poop particles in her vagina, often only discovered after you pull out your dick and see the poop on it. usually results in an immediate limp dick.
This often is caused by women who wipe backwards, from back to front, dragging the poop from their ass into their vagina, hence PooPussy.
A poopuss is a nasty twat that is brown and has stalagtites and smells like ass. This condition usually happens when the chick in question wipes from the back to the front instead of from the front to the back.
1) I went to chow down on her and I about gagged... she had a nasty case of poopuss.
2) Biotch, go wash that nasty poopuss before you come to bed...ya ho, ya.
3) When I looked at my face in the mirror in the morning, it looked like I been eating chocolate chip cookies last night, but it really came from a nasty case of poopuss.
