Abbreviation of
Taekwondo, which is Korean for "The way of the hand and foot." When
taekwondo is referred to as "
TKD," it is usually by those who think of the
martial art as a sport, which is a perversion of the original intent of its creators.
Although taekwondo is powerfull in the hands of those who use it correctly, those who treat the martial art as a game generally miss much of the things that this art has to offer. They are the ones that say "you don't want to mess with me, I'm a black belt!" or the ones that care more about rank than actually learning anything. By no means are all those who practice the art of taekwondo like this, though.
