The term "ollie" typically refers to a skateboarding trick that involves popping the board into the air without using your hands. This is done by slamming down the tail of the skateboard, causing the board to pivot on the front wheels, and then jumping with both feet to level out the board in mid-air. The ollie is considered one of the foundational tricks in skateboarding and is used as the basis for many other more advanced tricks. The term "ollie" is also sometimes used more broadly to refer to any jump or aerial maneuver performed on a skateboard.
