A wannabe mafia member (usually a snitch) or a wanna be gang member. A traposo usually wears the fake shit, or knockoffs. For example, instead of wearing Prada, the traposo would wear Prado Suits, instead of Versace, he would wear Versase. Usually the guy who just trys too hard.
That guy is a Traposo, ese.
