butt lava

Diarrhea. Not just your average diarrhea either. This is the kind that explodes out of your ass and leaves your butthole chapped for the next few days. It is a hot, burning diarrhea that smells worse than vomit. This is as bad as it gets.

I ate at Denny's tonight. I think I am going to have the worst butt lava tomorrow. I better take some imdodium.

Butt Heaving

Agressive diarrhea, more violent in nature than regular diarrhea, and where each episode requires a longer than normal visit to the restroom. Similar in nature to extreme vomiting after drinking WAY too much alcohol after a long night of partying except that material is ejected from the other end. (The word is funnier if pronounced "Buttheavin' ".)

Dude, why were you in there so long?
Sorry, I was butt heaving.

Don't go in there yet, someone was just in there buttheavin'.
