A sexual fetish where the male does the female anally while she shits on his dick. Then, the male removes his dick, wipes the shit around the asshole, and then cums in her ass. The female then farts out the cum, looking like a volcano :P
James: Dude, let's make a Krakatoa!
Alex: Dude, I don't think my asshole can handle that kind of shit!
James: Don't worry about it, it'll be fun :)
Alex: Alright, fine. But only if I can be on the recieving end :D

Molten diarrhea. Originating in southern Illinois, this type of bowel movement is incredibly dangerous and should not be taken lightly. At the slightest hint of krakatoa make your way to the toilet, there is no holding it. Krakatoa can be differentiated by it intense searing pain, watery eyes, and feeling of shame as you exit the bathroom.
