Your first poop at home after you return from vacation. Can consist of all-inclusive resort fare, airport snacks, or even airplane food, but it's the last thing you ate before you returned to reality.
Laundry's done. Got the dog from the kennel. Just took a souvenir poop. Party's officially over.
Post-Poop Butt Hurt is when, after a particularly bad poop, your butt hurts. Otherwise known as PPBH.
Person #1: Aw, man, I took such a big dump yesterday that it gave me PPBH!
Person #2: PPBH?
Person #1: Yeah, Post-Poop Butt Hurt
Person #2: Dude, PPBH is the worst!
