A warning call made after someone farts, accompanied by raising one hand vertically and placing the thumb upon the forehead as a means of immunity. The last person to call "buckeye" and complete the hand gesture is said to have "ate it". Another way of achieving fart amnesty is by calling gas cap/gas tank/stovepipe and walking to the nearest gas cap, etc. and touching that object.
