Bs Lipslides. I learned them pretty quick after learning backtails. Got overconfident and tried to do a long one on this flatrail hauling ass, slipped out and broke some fingers. So now every time I setup to relearn them, I get like Maverick in the last dog fight of Top Gun and I'm like "No, it's no good." and end up just rolling right past the rail. Its dumb because I still do nollie bs lips.
