Dirt Bunny 

A woman who dresses up in fox, monster or rockstar gear and attends motocross events for the sole purpose of pick up and fucking one of the riders.

Trisha wearing her fox jersey goes down to the local track every Sunday to find who ever took first place so she can fuck them, thus earning her the title Dirt Bunny
