|: I think that trick with the knee is named "pornstar" in the in-line language (in fs).
: You all know that my house is open. I'm nervous waiting for you and your family, biff.
Why would you be nervous? We promise to behave ourselves......a little bit.
Here in the U.S., an inliners' pornstar is where your feet are somehow like a mizou: Your front foot is in soul position, and your back foot is grinding on the outside boot or frame. I have personally never seen anyone do the trick with the knee other than you Spaniards. I keep meaning to learn that trick, but I always forget once I get to the skate park.
