Dumpster Sisters 

An endearing term given to a pair of females who have been around the block a few times, more like they are running the Daytona 500, but I digress, When the two ladies involved have both been pleasured by the same male, and subsequently have both had semen deposited (dumped) in their vaginal cavity (dumpster). In short Dumpster Sisters is the female equivalent to eskimo brothers.

BRIANN: Bitch I just got dumped in by this wing nut Cammy D.

CORINNE: Oh that punk, yup I hit that last week, weak form.

BRIANN: OH MY GOD, WE'RE DUMPSTER SISTERS!!!!!!!

CORRINE: Eh Had better
