The SOB who comes in while your working/sleeping/eating to make you want to crap yourself. It is possible to fight off diahrrea monster, but it isnt as easy to fight off as the sleep monster.
I was in the middle of a dream when the diahrrea monster snuck in and made me crap out my insides.

That was a viscious "Diahrrea Piledriver" Eric gave Teddy at the Christmas Party
When during the act of coitus, one rocks on some seriously heinous, turboblastular doo doo spray all up in their partner's domepiece. The noxious, miasmatic remains could be categorized as poo swampular.
It just seemed so appropriate... action was called for and I pulled a Diahrrea Pearlman right then and there, unloading my corrupt, fetid ass piss directly into her mouth.
