A spin on the name of the game, Fallout Shelter. A Fallout Shitter is when you go to the bathroom to release your bowels and start playing Fallout Shelter at the same time, but you get trapped in the game and forever stuck on the Fallout Shitter.
Bob: Yo, bro hurry up I need to pee! What's taking so long?
Bathroom Steve: One second dog, I'm caught in the Fallout Shitter! My Vault is being raided, a room is on fire and its spreading all while Death Claws are attacking me.
Bob: If you don't wipe soon you're ganna be playing dingleberry farmer!

Guy 1: Dude, I was in a Shitter showdown with that guy from the Repair Center for 15 minutes! He finally left, but now he knows who the real Crapper Cowboy is!!!
Guy 2: Yea, he's intimidating. He finally got me to give up after about 10 minutes last week.

Prolonged leaning forward on the elbows whilst engaging in iPhone gaming during the act of having a particularly tricky bowel movement. With the result of leaving a prominent red mark on the thigh saluting your efforts.
After a heavy drinking session on the Guinness, I was birthing a beast from my ass whilst trying to beat that tricky level on Angry Birds and it left me with serious Shitters Knee.
