Shattler

A loud, powerful fart that rushes around the feces as it departs the asshole, so it creates an air pocket and the crap rattles around a little before exiting.

Billy: “I was trying not to get noticed while taking a dump at the party and had a shattler, it felt kind of good, does that make me gay?”

Dave: “No, I love when I get a shattler, too bad they are so rare. If loving shattlers are wrong, I don't want to be right.”
