The
ollie is a technique of jumping on a
skateboard in a way that pops the board off the street by kicking the
tail section or the
nose (
nollie) section of the skateboard. This action lifts the opposite end of the board, at which point the front foot (in the case of an ollie) will slide forward causing the rear end to level out. Once this is achieved the rider lands all four wheels on the ground and rolls away with their knees bent.
