Get the Piss Stiffymug. by Crazy dum December 14, 2021
Get the mad stiffymug. When a heaps rough person leaves a nightclub in his undies asks ppl for a favour on their way to work but gets in a fight with a lawyer that’s also a secret ninja
That dude pitched a tent in his ripped undies and left the nightclub to touch a stiffy bro now we can’t say if he’s been knocked out or he’s having a Power Nap
