Bellaqueo is Spanish slang for intense flirting, teasing, or foreplay, often with a playful and sensual undertone. It comes from the verb bellaquear, meaning to tease or flirt suggestively, and it is very common in reggaeton lyrics.
In this song, Rauw Alejandro sings "Nos vemos y el bellaqueo" (See you and the bellaqueo), using the word to set up the flirty, charged mood of the encounter he describes.
Rauw Alejandro's "Sexo Virtual" is all about that intense longing and desire when you're physically apart from someone you're really into. He's tired of just seeing her from a distance, singing, "Estoy cansao' de siempre estar viéndote de lejos" [I'm tired of always seeing you from afar]. He's been imagining them together, even in front of his mirror!
This song perfectly captures the excitement and anticipation of a virtual encounter. He's planning a video call for some "bellaqueo" [flirting/naughtiness] that will end in "sexo virtual" [virtual sex]. He's wondering, "¿Me va' a dejar con las ganas o me las va' a quitar?" [Are you going to leave me wanting or satisfy me?], even though he can't physically touch her. It's a fun, flirty look at modern romance and how people connect when they can't be together in person.
