A request you ask of a friend or stranger when you are having such a bad day that the only thing that could make it worse is someone actually emptying their bowels onto you.
Wesley: Dude its too bad that you forgot to wear clothes on school picture day, now your ding-dong's gonna be in the yearbook.
Ben: Take a dump on me!
Wesley: Okay!
A twist on the saying ,"shit in in one hand and ask with the other and see which one gets filled 1st", targeted at complainers and whiners.
Whiney person: Everything sucks as usual.
Me: Complain on one hand, take a dump in someone's boot on the other hand and see which is more interesting to talk about.
Whiney person: That's the last time I complain to you about my life and also why are my boots in the bathroom?
