taking two shits in immediate succession of each other. taking yet another shit when you've just finished a shit. happens especially after a night of heavy drinking, when you've just finished a serious beer shit, the ass juice isn't yet evaporated, you're getting off the crapper and you realize you have to go again. can be used as verb or noun.

mostly occurs the morning after a heavy drinking session. When someone is sitting on the toilet clearing their bowels and they suddenly have to throw up as well - both "exit pipes" are in full flow as vomit and excrement both leave the body by their respective routes.

Usually accompanied before and after by groans of "oh god" "never again" or "oh shit" and requires someone else to clean up the mess as the double dumper is too worn out to do much more than wipe their ass.
did you here that ? sounds like "Johny" has just done a Double Dumper. I ain't cleaning that up
