Let's think about riding a skateboard.
You're skating your natural stance.. if you go up on the board and use your nose to pop it's a nollie. If you skate your unnatural stance its switch. If you're skating your unnatural stance and you use your nose to pop its fakie. If you transfer that to skis it's pretty easy to think about
Anything switch isnt considered fakie until you use your nose to pop but yeah skiing is weird. Unlike skating(mostly), I've seen people use different lingo for x and y tricks so I don't even bother when someone calls it different than me. Who cares. Fuck a 3, I'm doing helicopters!!
