A fat girl who can't turn down sex due to frequent rejection in normal circumstances, and ends up sleeping with any guy desperate enough to proposition a sexual encounter.
Hey where's Amy? She's at the Doctor again. That slutopotamos got chlamydia from sleeping with all those guys last week.

Jen, just because I don't sleep with every guy I meet doesn't mean you have to be a slutopotamos and sleep with them behind my back.
