Tornado Kick 

A Tornado Kick is pretty much a controlled chaos. it is a martial arts kick (TaeKwonDo) in which the artist turns 360 degrees and delivers a crushing blow to the opponents head.

guy who thinks hes tough: Hey dude wanna fight?

TaeKwonDo artist: No thats ok. i dont like fighting.

tough guy: *takes a swing at him*

TaeKwonDO: *blocks punch and knocks him on his ass by a tornado kick*

tough guy:*struggles to his feet, spits out some blood and teeth, and walks away crying to his mommy*
