Replying to Non-trolling/shitstorm question about trick-calling!

I just have one question about tricks like misties, rodeos, or corks and bios, are theycalled by the direction you huck your body? (forward or backwards) Or by the direction of your body in relation to the lip of the jump? (flipping towards or away from the lip) because I have seen it called both ways, I'm just looking for a clear answer as to which one is the official way! +K for legit answers!
