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!"

The Mop Bucket Dump is one of the most heinous of all acts of defecation. The anal sphincter opens to allow a virtual geyser of liquid feces to explode from the rectum and oring. The explosive force, sound, smell and the look of a Mop Bucket Dump achieves its notoriety from the that is looks no different than if a Janitor had emptied his or her filthy, used, dirty mop bucket water out into the toilet. Pure liquid dirt. You cannot tell the difference between the Mop Bucket Dump and a dumped mop bucket.

The Mop Bucket Dump is typically the result of poor dietary choices but may also be a result of food poisoning or other gastrointestinal conditions.
Steven thoroughly enjoyed his entrée of fresh, Norwegian prawns although he thought that they might have been a little off and rancid due to the smell and tangy after taste. About an hour later, he found his ass plastered to the toilet and arms gripping the handrails as he blew a wet, steamy, dirty, brown Mop Bucket Dump. As the sweat dripped from his brow, he realized that the prawns were in fact off.

A group act of defiance perpetrated by disgruntled employees, students or other activists that results in urine, rather than cleaning agent, to be unwittingly distributed on the floor of a relatively small, enclosed space; given sufficient time, the now ripened piss causes the air to become unbreathable, the facility itself rendered temporarily toxic.
