A kind of rollerblades. Not like ordinary inlineskates, and not like aggressives, but a sort of mix. Freeskates has way smaller wheels than inlines, but bigger than aggressives. It also has much better support for the legs than inlines, but no soul platesl like aggressives has. Salomon FSK is considered to be the best brand for freeskates.
The point with freeskates is to get from A to B, eluding all obstacles.
SOCL= Sitting on chair laughing. Invented by ehs5 under a msn-conversation because he thought that ROFL is so exaggerated. I'm pretty sure you don't actually are rolling on the floor and laughing when you write ROFL, if you laugh at all, you are sitting on a chair.
ehs5 invented the expression SOCL early 2005, since then it has been used by one other person so it became a little more famous.
