a surfer who inhibits the enjoyment of other surfers. can be done in a few ways:

1. snake people out in the water.
2. feel they have the right to put other people down because they arent as good of surfers as others
3. pick fights with people to make yourself feel superior
4. dont follow the rules of the water
