The act of intentionally holding in a fart. Like being dealt a hand in a poker game (the fart) and essentially just folding.
Folding a fart, fart folding, folded a fart, etc. all of which mean not being comfortable enough in the environment or with your own digestive system enough to realease a fart.

“I had tacos last night for dinner and I’ve been folding farts all morning. Trying not to poop my pants.”

“I had to fold a fart in the elevator this morning and now my stomach hurts.”
