fartreezing
When you really need to fart but you're in public so you slowly open and close your butt-cheeks while forcing out small farts. Sometimes this can lead to sharting if done to fast.
You: I REALLY NEED TO FART BUT WE'RE IN PUBLIC! WHAT DO I DO!
Friend: Try fartreezing, it helps.
You: Thanks man! It's really working.
