Splatter-house Ass grenade 

The explosion that occurs when a fart preceeds Diarrhea. Much worse than a standard Ass Grenade, The Result is a complete anal erruption spraying butt pee all over one's toilet and backside, with possible blood as well.

I hope I wiped thoroughly enough after that Splatter-house Ass grenade!
