dumpering

When someone you're dating is rude and disrespectful to you so realizing you'll probably be dumped sometime soon you abruptly end the relationship rejecting that person before he/she can reject you.

That gal treats me terribly breaking dates at last minute with lame excuses and ignoring me when we're at social functions so I'll be dumpering her today.

Rumper Dumper (Or Rumpy Dumpy) refers to a HUGE ass. I'm talking giant butt. Milked up butt cheeks, the whole nine yards.

titty dumper

A embarrassing prank where you grab the wire underside of a woman’s bra and pull outward and upward, causing her titties to be dumped downward out of the bra. It’s like a reverse wedgie, but for breasts.

Susan and I are always playing pranks on one another; when she leaned in to hug me today, I surprised her at the last minute by giving her the ol’ titty dumper.
