Peliculear is a creative, colloquial verb that literally means "to movie". It's derived from the Spanish word for film, película.
In the song, the line "Lo de ella es peliculear" means "Her thing is to be dramatic" or "She loves to make a movie out of everything". It's a fun and evocative word used to describe someone who creates elaborate, cinematic scenarios or fantasies, living life as if they're the star of their own film.
Omar Courtz is not playing around in this track! "FAYA" is a super direct and confident song about pure physical attraction. He's telling a woman he's into that she's "fire" and he wants to see her right now. The whole vibe is about being spontaneous and giving in to desire without waiting. He makes it clear this isn't a serious romance when he says, "Y yo sé que aunque no eres mía, tú te presta'" (And I know that even though you're not mine, you're down for it).
The song is full of details about a flashy lifestyle, with mentions of Miami, a chauffeur waiting in a Denali, and a room in front of the mall. He's basically saying, "Tú manda la ubi, yo voy" (You send the location, I'll go), promising to drop everything to meet up. It's a classic reggaeton party track that's all about the immediate thrill of the moment.
