When a snowboarder goes down a slope in the braking position, effectively the side of the board. A very slow way to go down advanced
slops, commonly looked down upon by advanced boarders.
Sideboarding is a technique commonly used by snowboarders not experienced enough to
ride down blue and black slopes properly.
Sideboarding has been known to wreck
moguls and create unwanted banks of snow for more experienced boarders.
Guy 1: Look at all those idiots
braking all the way down
the black diamond.
Guy 2: They're
sideboarding. It either means the snow on the hill sucks or they're just idiots who aren't ready for this kind of hill.
Guy 1: I'm gonna hafta go with the latter.
