A person who is struck by a debilitating case of diarrhea, explosive or otherwise, and has the misfortune of other stomach related ailments. While relieving said diarrhea the individual is overtaken by the sudden urge to vomit and is forced to do so into the already poo contaminated water. Upon contact with the water’s surface the projectile vomit splashes the contents up into the individuals face… they have just been shitfaced.
Dude, I can't go out with you tonight my stomach feels awful, plus I need a shower I just shitfaced myself in the bathroom.

Shitface is the look somebody gives after taking a shot of liquor. If somebody is shitfaced he/she has drank too much and their face shows it.
"Haha, you missed the shitface on that prick while you were in the bathroom!" or "im going to be sporting my shitface tonight"
