It's a sneeze, cough, & in-between those occuring, a loud fart is released. Usually an embarrassment to the farter but hilarious to others.
Man did u see Brian achoo-fart? That sneeze & cough made him fart so loud, that he may have shit his undies. Now we call him skids. He's a dick anyway.
It's not nice to point & laugh hysterically but sometimes, among friends who have a good sense of humor, u just have to. Be mindful & kind though.
