While intoxicated, you proceed to eat out a girl. You then vomit in said vagina. After emptying the contents of your stomach in her vagina, you then have sex with her. The resulting effect is like that of a mop in a mop bucket. Think of sloshing a mop in a bucket of dirty water.
"Dude, so we were so drunk last night, while I was going down on her, I puked right in her without her knowing. I then totally mop bucket-ed her and she didn't even know it!"
