Force kick

The term "Force kick" jokingly refers to a parttularly badly choreographed and shot fight sequence in Return of the Jedi in which Mark Hamill/Luke Skywalker kicks on of Jabba the Hutt's henchmen in the head, causing him to fall into the Sarlacc, whilst Boba Fett is flying helplessly by in the background.

The choreography flaw consists in the stuntman reacting to the impact of the kick too late when Hamil is already lowering his leg, while the shooting flaw consists in the camera being placed such that it is very obvious that the kick does actually not hit the stuntman.

The sequence is referred to as the "Force kick", jokingly speculating that Luke uses Force telekinesis to make the henchman fall into the Sarlacc rather than the physical impact of the kick. Of course, it is never suggested that the Force kick is an actual Force power in the Star Wars universe, and a retcon of the sequence along those lines is highly improbable.

The Force kick sequence sparked off a minor fad within the Star Wars oriented part of the YTMND community, in which the term might have originated.
