It's like an 'olly olly oxenfree' for your bowels, stomach and bladder. An involuntary reaction that causes one to vomit, shit and piss himself. This most often occurs during level 5 drunkenness or sometimes while sneezing violently.

It's rumored that grafundalo is an onomatopoeia of the sound one makes during the ordeal, or that it is a bastardization of an Italian word.
