plenty of names for kiting from surfers- ****en tea-baggers, dope on a rope, WAFI (wind assisted ****ing idiots), wannabe wakeboarders, and my favourite; "why would you do that? it just looks gay."
"kite sailing", "wind sailing" and then people make a wierd motion with their arms to demonstrate your sport. at school kitesurfing seems to be common knowledge even though there are 4 of us in a 1200person school happy kitesailing
I get windsurfer from a lot of people. I don't even bother correcting them any more. "Yes I am going windsurfing with a kite...." , even then they don't catch on.
