What is The "shit" Face?
1.
the awful churn of your face (and stomach) when you walk into a bathroom stall of a crowded bathroom right after the stall user before you's lunch was from an undercooked chinese place...
-or the look on your face after realizing the Chinese food was undercooked, and now passing its way down your esophogus :)
"Dude, it was awful I went into the Walmart bathroom today and was lucky to finally get a stall, but I didn't realize how unlucky I was. Man I almost lost my lunch after smelling that women's stomach contents. you shoulda seen the "shit" face.
