There was a guy we secretly nicknamed "Dirty Sanchez" on my men's rec league baseball team in the early aughts. He was a Mexican guy who was just a complete scuzzball - he, no lie, owned a used car lot. (Insert cute lawyer-related retort here.) Also happened to be the only player who was assigned to us and not recruited.
The name fit perfectly. At some point, I believe that he was in the Police Blotter for pulling a gun on someone somewhere. He could pick it a little bit, though, so we let it slide.
