A slang term for a vagina. Usually used in regards to what a heavier woman with an ugly face, one you can't imagine actually having sex in any way, would call her own vagina.
"What do you think Nikki calls her vagina during sex?"
"She's probably like 'Oh, yeah! Stick it in my big-girl mouth!'"
"She's probably like 'Oh, yeah! Stick it in my big-girl mouth!'"

Only the best Ska band to hit the streets since the once who own the pumped up kicks. Elvis Presley couldn't hold a spoon to this group of Somalian Gods. It was once said that the bassist actually plays with an actual bass even though he has never been seen since he plays in a pool of swamp water when performing live.
