When you release a hot fart into your hand while you have it cupped over your butthole to catch it, then release in the face of someone.

It's what's on your finger when you stick it in your butt crack and rub really hard near your butthole.
After a long butt scratching session, I like to smell the bunk on my fingers, then rub it on my boyfriends face. He eats it up!
