Boté comes from botar, which literally means “to throw away” or “to toss out,” but in this song it is used colloquially to mean “I dumped you” or “I cut you out of my life.” Its blunt, memorable wording captures the song’s theme of decisively letting someone go.
Te Boté is a breakup song where the singer keeps insisting he is over someone, while every other line proves he is not.
The hook is the title phrase: "De mi vida te boté" (I threw you out of my life). Botar literally means to throw away, the way you toss out trash, so it is a blunt, almost cold thing to say about an ex. He doubles down with "Te di banda y te solté" (I cut you loose and let you go), where dar banda is Caribbean slang for giving someone slack or letting them go.
Then the verses undo all that confidence. He spends "muchas noches pensándote" (many nights thinking about you), and admits "Me pasaré la vida entera preguntando a dónde fue" (I'll spend my whole life asking where it went). There is a petty twist too: her friend texts him and snaps a photo with him "pa' que tú la vea'" (so that you see it).
The chorus line "Pa'l carajo usted se fue" (you went to hell) is rude, so keep it for karaoke. Notice the dropped letters as well: pa' for para and vea' for veas are how this Puerto Rican style of Spanish actually sounds.
