Polite way to let a friend know that you need to leave some place fast because you LITERALLY shit your pants (
sharted)or FIGURATIVELY
shit the bed. If you just farted up the joint and need to leave you might say "night's over" as hyperbole.
a: Night's over.
b: Why?
a: I pooped my pants so lets get outta here fast.
---------------
a: Night's over.
b: Dude, we didn't eat all day, how'd you shart.
a: I didn't shart, I just got rejected hard by the shot-girl, though, so we gotta bust outta here.
--------------------------
This derives from the classic line in the movie 25th Hour: "Night's over. I sharted."
