Vert kicks that takeoff using the "swing" transition. Like the it's "Pop Kick" counterpart, swing kicks can take off in (roughly) frontside or backside. However, in mainstream, these names are not differentiated, and are treated like a "variation" of each other. TKT (True Kick Terminology) separates the swing vert kicks based on takeoff, and the TKT equivalent naming system can be found in the description of each individual trick.
