When you mean to do something really obvious but then you forget what you were doing and end up doing something something completely different. i.e, when you have a wrapper in one hand and food in the other, and throw away the food and try to eat the wrapper.
Brain Fart:
Person 1: Man, I had such a brain fart today.
Person 2: What did you do?
Person 1: I was holding food and a wrapper and threw away the food and tried to eat the wrapper.

A friend who will laugh with you when you fart, no matter how rancid the smell, while everyone else leaves the room angrily.

When you press your butt against a hard, flat-surfaced chair and fart, but there is no place for the gas to escape except up the crack of your ass. and out at the top.
Dude, I laid the biggest periscope fart in detention. I press my butt cheeks against the hard chair and farted and the gas came bubbling up the crack of my ass and peeked out at the top!
