Pronounced: poe-poe snah
Shit that remains on someone's ass just after they've taken a dump and have not sufficiently wiped their butt. It's still moist and stinks. Frequently encountered in office environments. Someone with popo sna walks past you and smells like they shit in their pants. Can be a rude awakening to someone who eventually drops trow and see the stains in their underwear.
Did you get a wiff of that guy?! Every time he drinks coffee, he hits the head within minutes. Musta forgot to wipe his ass, I can still smell the popo sna. Anybody got a match?
