When a man is engaging in anal intercourse with a woman, and then swiftly pulls out and plows her vagina, filling it with her own feces.
Dude, I had this fine ass chica last night, and I totally gave her the poopgina.

A vagina that is filled with feces. Whether it be human or not. The poopgina sometimes leaks more liquid based feces. This is the best case scenario.
I gave Barbara a poopgina, it started leaking. I thought her vagina was crying. This made me sad in the pants as well.
