a sick ass, psychopathic assassin, with souped up weapons and more ninja skills than sonny chiba. there's a 90% probability that he will kill your ass if you see him.
noted for being in the movie "no country for old men"

Dude, I gave my gf the "Anton Chigurh" last night, nearly blew her brains out.
