Slopabottumus 

When you're drunk and you can't be on top because you have limited motor functions. So you offer to bottom like a starfish.... but then the jackhammering causes sickness... and then shit gets sloppy.

Kelly: SO totally saw that you houdini'd out with that guy last night, did you?.....
Sarah: .... I was a total slopabottumus on that one. I didn't even ask for his number. I just bailed.

Slopabottomus 

The ultimate bottom. Loose hole that has been filled by large cock often.

As seen in william belli's "This boy is a bottom"
"Ass up and pull your pants down"
Wears a jock strap on the first date

Gay Male Friend 1: Hey, you know that guy i hooked up with from grindr last night?
Gay Male Friend 2: Yea, you said he listed as verse right?
Gay Male Friend 1: yea, but that guy was a total slopabottomus.
Gay Male Friend 2: I bet his farts sound like someone blowing air through a donut
