a shittypasta is a wanna-be creepypasta written by a 10 year old about something that's supposed to be creepy for others. usually they only rely on body horror and a shit ton of other clichés while piggybacking on something famous.
The result of a badly-timed, pre-toilet-roll-shoppoo in which the only surface with which you can clean your shitty arse is the palm of your hand
You've just got out of the shower and feel the familiar rumblings of a forthcoming diarrhea attack so after making sure the toilet door is locked, you sit on the toilet and unleash the fury, legs spasming uncontrollably and all. When this violent exchange is concluded you look around and to your horror see that there is no toilet roll. You think about using the good towel but decide it isn't worth your life so you close your eyes and send your palm to it's untimely, shitty death. Shitpalm.
The act begins with two lovers each individually shitting their pants. They then remove and trade pants, quickly putting on the others' steaming shitty pants. This is followed by an extended period of dry humping.
Burt: Yo dude, I owe you a new pair of pants.
Will: Why what happened?
Burt: Last night me and that stripper I brought home played shittypants switchypants with your new jeans.
Will: Dickhead.
