look up any word, like dirty sanchez:
 
1.
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!"

Daft cunt, idiot, Some one who's always fuckin' up getting things wrong or mixed up. This person will often be funny and most probibly liked - one of the lads.
He's a proper 'Mop Bucket' when he's pissed. or , for example, when somebody spills the last of the ale will often be followed by "What a fuckin' mop bucket!"
