RBSD

An acronym for Reality Based Self Defense, it is used by such martial arts as krav maga and is supposed to take situations that would occur commonly in a situation involving mugging and/or rape or other forms of assault on the street.

Usually it is defined by eye-pokes, groin grabs, and other desperation techniques.

krotty

The slurring of the word karate, often used as an insult.

Also used by many practitioners of full-contact karate schools to denote those who claim to be karate, yet train ineffectually while claimed d34dly-techniques.

Ironically it is people who do krotty who often are the loudest defenders of their schools and krotty systems, karate practitioners let the KO's speak for them.
Bill: Dude! I got a black belt in KARATE

(Bob proceeds to kick Bill's ass)

tkd

Also known as Tae Kwon Do it is a foolish and inneffective martial art that also happens to be the largest in America. TKD is not effective and should not be taken seriously.
