It's all good! The "DORYA" shirt references a move from Tekken that is extremely iconic. "DORYA" is the sound he makes when he preforms said move.
The token design is just a dirty arcade token, "PLAY DIRTY" is BROKENTIER's unofficial slogan. It has some really subtle imagery in it relating to some old fighting games. And the katakana shirt is just for fun, because I'm obsessed with Japanese typography. Remember, a lot of my stuff is aimed at extremely narrow targets; some groups don't understand it at all depending on when you got into the scene, or what games you play.
Doesn't lead to a very profitable business, but I enjoy people who get it, and really enjoy it. :D
