Really? Because i think calling it some made up name sounds straight retarded. It IS sliding a rail, so why not call it sliding a rail.
It shouldn't even need to be mentioned because it is the most basic. Saying "270 out" gets the point across, saying, "i slid that 5 kink" gets the fucking point across
This is like saying, "we need a sweet name for straight airing a jump!"...it doesn't even need to be discussed
