My Irish friend refers to them as "Air Biscuits." So whenever he farts he just elbows me and says "air biscuit." Everyone around us is so confused and I'm just like "DUDE!!"

I only fart when I'm nervous, in which case there's no stopping them. They're usually the silent but deadly type too. Though occasionally when it isn't a nervous fart and I'm like in school, I try to make it silent because there's no way I'm getting to the bathroom in most of my classes.
