When a small group of people bust ass, and no one knows who did it
What is not a soul gonna claim that awful stench? Must be a "farty boy mystery!"
A younger brother who doesn’t answer your text messages, farts way too much and probably has IBS. Farty boys are so stinky that they make the air reek of farts wherever they go and they suck at playing Mario Party.
Aka - a stinker.
Good lord it stinks in here, a farty boy must’ve passed through!
