holding afterbang to long once you've landed a big air on you snowboard. It's about as attractive as pee shiver after holding your pee in for an extra two hours and you have to just pee in public just so you won't pee your pants. Avoid postbang at all costs (unless you want to get laughed off the mountain).
did you see that clamer? He held his afterbang so long it looked like his spine was made of jello. Postbang looks so bad that dumb ass!!
