**Locochón** is a playful, intensified version of the word loco (crazy). The -chón suffix is an augmentative, used here to mean something like 'the main crazy one' or 'the big crazy guy'.
In the song, the line "Tú mi loca y yo tu locochón" means "You my crazy girl, and I your big crazy guy." It's used as a fun term of endearment, highlighting a passionate and wild connection between two people. This is a great example of creative, modern slang you'll only learn through music!
This song is a super direct invitation to a secret night out. FloyyMenor, an artist from Chile, isn't wasting any time with subtlety here! He kicks things off by telling a girl, "Mami, te siento lejos, dime dónde estás" (Mami, I feel you're far away, tell me where you are), and then immediately gets to the point with the very bold line, "Te quiero chingar, te voy a raptar" (I want to f*ck you, I'm going to kidnap you). He's basically telling her to drop everything, turn off her phone, and let him sweep her away for the night, promising that "si estás conmigo no te va a pasar na" (if you're with me, nothing will happen to you).
The whole vibe is about a spontaneous, rebellious escape. He's confident she's into him too, saying "yo quiero contigo y tú quieres conmigo" (I want to be with you and you want to be with me). The lyrics are full of modern slang and references, like asking her to "mándame tu ubi" (send me your location) and dance to the "ritmo del TikTok" (rhythm of TikTok). It's a song about intense, immediate desire and convincing someone to leave their world behind for a secret adventure where "en su casa nadie lo notó" (at her house nobody noticed).
