A carnival worker. Usually an adult male or female missing two or more teeth or possibly missing two or more of their limbs. They are masters of their craft which usually involves pulling a lever to make a ride move or pushing a button to make a ride stop. Most carneys enjoy a tasty marlboro red and the beer of their choice while operating the rides.
Bob: Hey lets go ride the ferris wheel!
Sue: We can't. The carney operating the ride is passed out.
