Was  my twin brother a poser or a real skater?

My twin brother used to skateboard alot when he was a kid.  However many other kids called him a poser.

So my brother would

• skateboard often (go to a skatepark sometimes and skate while he was there)

• know the difference between a regular and a goofy stance

• know the difference between the nose and the tail of the board

• often dressed in skater shirts 

• dressed in skinny jeans

• dressed in skater shoes

• dressed in skater hoodies

• wore a skater helmet (as opposed to a bicylce helmet)

• knew what an ollie was and would ollie HIGH 

• not bad at skateboarding (he impressed some people.) 

• he listens to a variety of music

• he never smoked or did drugs as a kid (well except he once drank alcohol as a kid)

• he dressed in army boots as well as abercrombie sometimes

So was he a poser or a real skater?  Alot of kids would call him a poser (compared to other kids who skateboarded).

I'm not gonna state my opinion, I want to know what others would say?
