What does pincha puto mean in spanish?

Type your answer here... The expression "pincha puto" is used in Argentina, and is simply an insulting way of addressing a fan from the football club Estudiantes de La Plata (the "pinchas", short form of "pincharrata"). The Word "puto" is basically a generic insult, ranging in meaning, depending on the intention and emphasis, from "moron" to "jerk, coward, traitor" and other stronger ones that I cannot type here.
