There are 2 kinds:
1. Real skater, that respects other sports (BMX, aggressive skate). Usually, these people are decent skaters.
2. Poser. These people hate "spacewasters" and "fruitbooters" to assuage there own feelings of self loathing. These people can be found sitting on top of a quarterpipe, wondering if they might get hurt trying an ollie.
Poser: OMG! That faggot fruitbooter just ground 8 feet of pipe rail (coping). What a noob!
Skateboarder: Then do it.
Poser: I will, as soon as I figure out this whole dropping in thing.
