dumpee- one who gets dumped by their partner in a break-up
dumper/dumpee: The bad news about being the dumper is that you need to be certain it's over before pulling the plug / As the dumpee, you get lots of attention and have every excuse to feel sorry for yourself.
OMG...we were having some really hot sex in the shower after our date and then he tried to do me in my backdoor. Watch out for him, he's a dumper rusher.
Dirty anal sex. It was first pioneered by the Gap Tooth Pirate, Cromer. Before ejaculation, the man pulls out and cums on the girl's face, because "she knew it was coming".
