A shady or untrustworthy person who acts only for their own profit, usually by deceiving others (in Argentina, this is commonly used to describe a scammer or a dishonest person).
Person A: I am going to buy a cell phone from the shop on the corner. Person B: Do not go there, he is a tranfuga.
1. A heavy blow, hit, or smack. 2. A reference to a cheater (referencing Roberto Madrazo, a Mexican politician from the PRI party who famously cheated in a marathon by taking a vehicle to the finish line and splashing water on himself to look sweaty).
That dude got hit with a hell of a Madrazo. He cheated just like Madrazo.
A man who pursues his own selfish and material interests through immoral means and openly boasts about his disloyalty. This vulgar term is a blend of words for a shady character, a filthy person, and a man who frequents prostitutes.
Those two putarracos were bragging about how many times they had stiffed the prostitutes whose services they had used.
