It was a large, drunk "chicano" man in a large red t-shirt. He kept saying he is "chicano" and trying to prove how "chicano" he is by starting fights. [I do not think this word means what'chyou think it means]. He was trying to start a fight with one skinny kid by talking drunk non-sense when a larger man in black told him to shut up. But, being drunk and beligerent, he was not about to. It escalated to the point where our drunk "chicano" man in red was punching the bus. He broke the metal grate on the ceiling. The entire back of the bus cleared out.
