McDojo
A martial arts school that puts the profit motive as their highest priority. This inevitably leads to a watering-down/bastardization of the art which is the most common source of fresh (non asian-superstition derived) bullshido. 

Most schools in the states are McDojos, though no school (or student of a school) will admit to being a McDojo. The exact qualifications to be a McDojo are thus highly contested. However, one thing is for certain: every Tae Kwon Do school is a McDojo (don't try to argue, you know it's true).
I learned TKD at a McDojo.
