Tatuajito is the diminutive form of tatuaje (tattoo), literally meaning "little tattoo". Adding the suffix -ito is common in Spanish to imply smallness, cuteness, or affection.
In the song, the line "Muéstrame ese tatuajito secreto que no se ve" (Show me that secret little tattoo that can't be seen) uses this word to create a playful and intimate tone. It suggests a hidden, personal detail, making it a key word that captures the romantic and flirty vibe of the track.
In this remix, Puerto Rican superstar Rauw Alejandro teams up with Camilo for a smooth reggaeton track all about being completely obsessed with someone. The song is a direct and flirty declaration of desire, focusing on how amazing this person looks, especially their face and a specific tattoo. Rauw and Camilo are so taken by this person that they say, "Tú / Estás pa' comerte toda, todita" [You / You're good enough to eat, all of you]. They feel like they need nothing else in the world as long as this person is around.
The lyrics get even more intense and personal. They talk about being captivated by "Tus ojos color café" [Your coffee-colored eyes] and wanting more than just friendship. Camilo gets straight to the point, saying he wants to know about a "tatuajito secreto que no se ve" [secret little tattoo that can't be seen]. Rauw takes it a step further with a pretty bold promise: "En las costillas me tatúo tu nombre" [I'll tattoo your name on my ribs]. It's a song about that first rush of attraction when you find someone so irresistible you'd do just about anything to be with them.
