A take on triptych, a Tritick is a three sided sign of some sort. It could be a gang logo, a street sign (yield) or any three sided object that means something.
Common uses of a Tritick include many three-color flags, and some more complex graffiti may include letters written in Tritick. Letters are compressed and warped so that they look as if they have only three sides.
