A person who has surpassed all previous notions of sloppyness, they have become so quickly intoxicated and so sloppy that they leave behind a path of destruction equal to that of a dinosaur. Often they deny their sloppyness and continue to increase it.
Broski: Dude, that girl was such a Slopapotamus last night!

Broseph: No. She stole and kept that whole bottle of vodka to herself, broke the coffee table, smashed her face off the wall, ran around naked, puked, called her ex at least five times, cried, was temporarily suicidal and then passed out on the toilet. That bitch was a full on Slopasaurus!
