Pop Kicks are the basic building block of vert kicking. They takeoff in either frontside or backside, and are denoted by the naming system "backside #" for vert kicks that takeoff in backside, and "pop #" for vert kicks that takeoff in frontside. Numbering convention for counting the amount of rotation is inaccurate and unhelpful, but has stuck around due to tricking "tradition". TKT (True Kick Terminology) seeks to fix this issue, and the TKT naming counterpart can be found in the description.
