Teso is a popular Colombian slang word that means someone is very skilled, tough, or a "pro" at something. It's the kind of word you learn from locals, not from a textbook.
In the song, Bozá sings, "Dicen que soy bandido y soy muy teso" (They say I'm a bandit and I'm really tough). He uses it to build up his "bad boy" reputation, which he then says he forgets all about when he's with his love. Learning this word gives you a cool piece of authentic slang!
Panamanian artist Bozá is completely captivated by a woman in his reggaeton hit "Hecha Pa' Mi." He sees her as his perfect match, repeating the line “Estás hecha para mí” (You’re made for me). He's not just attracted to her looks, which he says “a mi mente envuelve” (wrap up my mind), but also to her unique personality. She's independent and quiet, with her own way of seeing the world. She lives by the motto “cosas vienen, cosas van” (things come, things go) and walks “sola y sin clan” (alone and without a clan). For him, she's a calm center in a chaotic world: “en un mundo de guerra / Solo tú me das paz” (in a world of war / only you give me peace).
The song is also very direct about their intense physical connection. Bozá admits he has a reputation as a “bandido” (thug), but says she makes him forget all that. He's so into her that he says, “Si no es amor, entonces que sea sexo” (If it's not love, then let it be sex). He feels like a prisoner in her house, “Condenado y sin proceso” (Sentenced without a trial), completely under her spell. It's a song about finding that one person who changes everything for you.
