Bichote is a Puerto Rican slang term that refers to a powerful individual, often associated with drug trafficking or someone who has achieved significant success and influence, a 'big shot'.
In the context of
Brray's "Bichotes Con Clase" is all about living large and proving his success to anyone who doubted him. He's not holding back, enjoying life to the fullest "por si no hay mañana" [in case there's no tomorrow]. He's got his loyal crew, his "hermano'" [brothers], and he's definitely not looking back at old friends who weren't there for him, saying "To' el que me tiró la mala se quebró" [Everyone who threw bad vibes at me broke].
He's feeling good about his come-up, especially since his "bolsillo engordó" [pocket got fat]. Brray isn't shy about his confidence, even if it bothers some people. He challenges anyone who can't stand his success, asking "¿Por qué frontean sin tener torque?" [Why do they front without having torque?]. It's a bold declaration of his status, showing that he's a "bichote con clase" [big shot with class] who's made it to the top.
