A Shove-it (or shuvit) is a skateboarding trick where the skateboarder makes the board spin 180 degrees without the tail of the board hitting the ground, or more, under his/her feet. There are many variations of the shove-it but they all follow the same principle: The skateboarder's lead foot remains in one spot, while the back foot performs the "shove". The pop shove-it was originally called a "Ty hop", named after Ty Page.
A shove-it is performed by standing on the board, jumping up a bit and scooping the tail down and to its side. Even though the tail should not touch the ground and the board should not lift off the ground more than about an inch, the board should quickly spin 180 degrees. The skateboarder then catches the board with his or her feet after it has completed the 180 degree rotation and lands on it. There are 2 types of shove-its, a frontside (when the user pushes the tail of the board forward with their back foot) and a backside shove-it (when the user pushes their back foot backwards as if to jump forwards). A backside shove-it (commonly shortened to just shove-it or shuv) is performed by putting the back foot with the toes hanging off of the front of the board, and doing a short, but quick movement spinning the board underneath the user. A frontside shove-it (commonly shortened to frontside shuv) is when the users toes and the ball of the back foot is on the board. The user then pushes, or kicks, their back foot forward to cause the rotation.
The 360 shove-it (or 3-shove) is a variation of shove-it where the board spins a full 360 degrees. Pop shove-it is a variation of both the ollie and the shove-it. The 540 variation of this trick was invented by Jasper McLean in 1979.
Unlike a shove-it, a pop shove-it starts like an ollie, as the skateboarder jumps and kicks the tail of the board down to make the board airborne. The trick then proceeds like a shove-it, with the tail kicked clockwise or counter-clockwise to make the board spin.
During a pop shove-it, the board reaches a greater height in the air than during the execution of a usual shove-it; thus, it can be performed while jumping over obstacles. Like any rotating trick, the pop shove-it can be performed frontside or backside.
