Groserías translates to "swear words," "profanity," or "rudeness." It's a fantastic word to know for expressing when something is vulgar or impolite.
In this song, Rels B uses it in a very self-aware way. After a few explicit lines, he sings, "Perdona groserías" (Forgive my swear words), directly apologizing to his lover—and the listener—for his language. This clever, meta-lyric is an intriguing hook that makes you want to hear what he has to apologize for.
Spanish artist Rels B skips the polite morning pleasantries entirely on "Cómo Dormiste?". Instead of starting the day with basic manners, he wants to jump straight into bed: "Prender sin decir 'Buenos días' / Hacer el amor y después preguntarte" ("Light up without saying 'Good morning' / Make love and then ask you"). The central hook is sweet on the surface—"¿Cómo dormiste, bebé? Si me soñaste" ("How did you sleep, baby? If you dreamed of me")—asking if his partner woke up craving him even more. But between those cozy morning questions, the verses turn totally explicit.
Rels B packs the track with playful, boastful slang and pop culture nods. He jokes that her body is "Hecha de laboratorio como Dexter" ("Made in a laboratory like Dexter"), shouting out the classic cartoon Dexter's Laboratory. When things heat up, he drops a fashion reference, noting her skin ended up bright red like the streetwear brand: "Se le quedó el cachete rojo, Supreme" ("Her cheek turned red, Supreme"). He switches between English club phrases like "so fresh, so juicy, so clean" and heavy Caribbean slang, calling for dembow rhythms and using the Puerto Rican vulgarity "bicho" (cock). He even pauses to laugh at his own lack of manners—"Perdona groserías, se me olvida preguntarte" ("Forgive my vulgarities, I keep forgetting to ask you")—before looping right back to that charming morning check-in.
