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!
