Picture this: a woman is a few drinks in at a bar when her ex walks in with his new girlfriend. Her response? Not to hide. She tells the waiter, "Garçom bota minha mesa lá do lado dela" (Waiter, put my table over there next to her), because she's about to spill everything. "Já bebi todas mesmo" (I've already had all the drinks anyway) is her excuse, and honestly it's a pretty good one.
The chorus is the best icebreaker ever written: "Prazer, eu sou a ex do seu atual" (Nice to meet you, I'm your current boyfriend's ex). Atual here is slang for someone's current partner. She warns the new girl she's "num beco sem saída" (in a dead end) and that "ele vai ferrar com a sua vida" (he's going to screw up your life). The final twist is the sting: "Ele me chamava de amor e me traía com você" (He called me love and cheated on me with you). So the new girlfriend was the other woman all along. Petty, funny and very sertanejo.
