train wreck

When explosive diarrhea meets a chocolate shotgun (look up separate definitions)- feces explode out of the rear with such incredible force the victim is propelled up and off the toilet, causing crap to be thrown/splashed in all directions and contaminating the entire bathroom, including mirrors, shower, sink, and, in bad cases, the ceiling.
1) Dude I got a charlie horse in my thigh right when I had a chocolate shotgun, and now there's been a train wreck in your bathroom. Good luck with the resale value bro!
