The ollie is a skateboarding trick where the rider and board leap into the air without the use of the rider's hands. It is the combination of stomping, also known as popping, the tail of the skateboard off the ground to get the board mostly vertical, jumping, and sliding the front foot forward to level out the skateboard at the peak of the jump.
