Shit On My Ass (etymology: Mod. English; portmaneau of the phrases "shit" and "ass," with "on my" forming the liaison) is a vulgar phrase expressing an utter discontent in an occurence, (e.g. where the conjuction "Shit!" would be used). Offshoots may include: shit on my dick, shite on my arse, holy shit on my ass, and the extremely long "piece of shit motherfucker on my ass."

When you're in a pissed off mood.
Similar to when you're constipated and can't quite get all the shit out of your asshole. The wiping never ends.
