Not to be
confused with the derogative term,
fatass, a shatass is someone who has eaten excessively to
the point of immensely needing to shit.
Guy 1: Where we tryna eat?
Guy 2: I don’t know
dude... I’m down for anything other than Mexican food.
Guy 1: What’s wrong with Mexican food?
Guy 2: Last
time I ate a
burrito, I nearly shat my brains out.
Guy 1: Haha, you’re such a shatass!
