An operation performed by Buttgina surgeons which creates a single passageway between butt and vagina!

buttgina 

when a womans is so fat, that her fupa covers her vagina. therefore creating the illusion that her vagina has actually migrated to her backside, located underneath her rear end. it is usually noticable when she is wearing sweatpants

f, " good grief, that woman has absolutly no business wearing a pair of pants like that. what on earth is that cleft of fat hanging off the bottom of her butt?"

me, "that my friend is a buttgina!"

When you are having sex and the penis falls out of the vagina and goes in the butt and then you stick it back in the vagina.

I was having sec last night and accidentally slipped into my girls butt then put it back in her buttvigna.
