Cho-geri of "the butterfly kick" as it is called in English, is a more advanced Taijutsu move employed by Jack Fletcher in the Way of the Warrior during the fight between him and Raiden.
Cho-geri was only used officially twice in the series. Once as mentioned above, and the other in Ring of Wind, when Jack is pitted against a pirate sumo wrestler, but misjudged the distance and missed,from lack of practice.
Description
It is a hard kick to master and involves launching your entire body off the ground, hands and legs rotating in a way that is not disimilar to a butterfly, hence it's name.
