Usually found on the WV Turnpike in a convoy of mini-vans traveling 45 MPH in a 70 MPH zone(It is a scientific fact that buckeye's are the worst drivers in the world). The typical family has all contents of home tied to the top or strapped to some home made bracket on the back of the vehicle.

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.
