A Sloppopotomus is a drunk, fat girl that tries to get with you at the bar. Sloppopotomus is derived from the latin: sloppimus maximus opottomus, meaning fat sloppy pig.
Most likely she will give you a rimjob without asking, dont worry about being clean down there, that soppy bitch wont care anyway.
Yo, i was at the club and this sloppopotomus waddled up and was all up on me. She was hammered and tried to jersey turnpike on my dizzle. She bent over and i swear i could smell her stank puss!
