0 someone who rides on a skateboard (= a flat narrow board with wheels underneath) that is longer and slightly wider than the usual type:
The county banned longboards from the canyon after an accident where a longboarder hit and injured a girl.
The longboarder can cruise urban streets with an environmentally-friendly and inexpensive form of transport dubbed "traffic surfing".
A lot of longboarders are asking for shorter boards for days when the swell's up.
"It's mine, it's mine", a longboarder shouts as he manoeuvres his board in front of the oncoming wall of water.
