A honourary title given to the ugliest girl in school. In particular areas, there may only be one roadkill per two or even three schools.
If any possible contenders rise up through the ranks from primary school, a fight to the death should be initiated. The winner gets to be continually mocked and jeered for mother nature's cruel joke vis-a-vis their face.
When she leaves school, her real name (if it can be remembered) can be used again, and a new roadkill instated in her place, with possible capes and crowns - but, to be honest, most people CBA
and just want to get down to the jeering.
'Hey roadkill, here's some money, please get a tramp to knife your face in - it's not quite plactic surgery, but it'll make things a hell of a lot better.'
