Feo literally translates to "ugly", but in this song, the word is reclaimed and used with a sense of pride. It's the central theme and title of the track.
The chorus states, "todas las mamichulas tienen su feo" (all the hot girls have their ugly guy), suggesting a 'beauty and the beast' dynamic. The singer embraces being the 'feo' for his partner, turning a negative adjective into a term of endearment and making it a very memorable and intriguing word.
Puerto Rican artist Lenny Tavárez and Prince Royce team up for "TU FEO", a playful reggaeton track all about landing way out of your league. The song turns a common Latin American running joke into a full-on anthem: "todas las mamichulas tienen su feo" [all the hot girls have their ugly guy]. Instead of pretending to be some flawless heartbreaker, the singer leans into the humor of the situation. He knows his luck is ridiculous, admitting that if he gets to be her guy, "más yo me la creo" [the more I believe in myself / the bigger my ego gets]. Even if she tells lies, he admits "por la forma en que me miras, yo te la creo" [because of the way you look at me, I believe you].
There is some extreme devotion mixed with luxury flexes here. He claims he would take a bullet straight to the chest without even wearing a vest, promising to treat her to high-end designer brands like Balenciaga and Fendi, and picking her up in a Royce (a clever nod to the luxury car Rolls-Royce and Prince Royce himself). The phrase "me voy a fuego" is Puerto Rican slang meaning to go all in, without hesitation. It is lighthearted, cheeky, and makes being someone's "trophy" sound like the best prize in the world.
