I'll shit 'em
You're not as good as you think, and I'm gonna show you by doing it right and then giving you a poop surprise.
You think you're the best at this game? I'll shit 'em and win the match.
You said you'd beat me in the test? I'll shit 'em and get an A.
You said you'd finish the work first? I'll shit 'em and be done before you even started.
