There is no such thing as Cab in skiing so people need to stop fucking saying it same with fakie.  Cab in skateboarding is spinning while you are riding fakie which is riding the board in the same stance that you normally skate but backwards so that when you olley you puch your front foot down and slide your back foot thus popping of the nose of the skateboard.  Cab in snowboarding means a switch frontside spin where you spin off the nose of the snowboard.  Nobody, far anyways, spins off of their tails while riding switch, in skiing.  End of argument.
