1.) Someone who wears baggy clothes, i.e. hoodies, jeans etc. These so-called 'skaters' can't always skate, but townies like to call them skaters because they reckon it's an insult.
2.) (the REAL definition) Someone who loves to skate (and can actually do it), not just some poser who thinks they are a skater just because they wear skate clothes. A skater can be anyone - grunger, goth, hippie, punk, mosher or even a stupid townie.
Darren is a real skater - he can actually STAY ON his board for more than 3.02 seconds.
