Someone who seems to be possessed, and can not stop skateboarding for thier own good.
Ex. "John broke his leg yesterday, but i think he was trying to skate again today... wat a board slave."
The time of day ( usually between 4pm and 6pm ) skateboards are drawn outside to skate by almost instinct.
Ex. "Wow man, i didnt even expect anyone to be outside when i got here, it must be board time."
