a stupid person-comes from 1970's UK crippled children that had to wear leg braces, one foot hit the ground normally the other went smack because of the weight of the calipers up the leg

The action of taking any object (preferably solid like a snowball, baseball, hand full of nails) and launching them as hard and as fast as possible at a passing car. Do not do on major highways. The term "smacking" is derived from the loud boom created when the object smacks the car.
Hey Robbie I was smacking cars yesterday with a piece of firewood and it smashed the windshield. Cops came fast like 5 minutes.
