Regaste comes from the expression 'regarla', a common slang term meaning 'you messed up' or 'you blew it'. Its literal root, the verb regar, means 'to water' (like a plant) or 'to spill'.
In "0 SENTIMIENTOS," the singer laments, 'y aún sabiendo que tú la regaste' (and even knowing that you messed up), calling out his ex for her mistakes. This is a fantastic and very common piece of slang that will make you sound more like a native speaker.
“0 SENTIMIENTOS” is a modern heartbreak anthem wrapped in the lively sounds of Regional Mexican music. Grupo Frontera and Fuerza Regida paint the picture of someone who gave everything—designer bags, paid vacations, time, and genuine love—only to discover their partner was never truly invested. The chorus shouts a blunt confession: the protagonist now feels zero emotions, casually firing off “TQM” (te quiero mucho) texts without meaning a word, because betrayal has numbed every warm feeling he once had. These lyrics blend raw honesty with tongue-in-cheek bravado, turning heartbreak into a sing-along moment you can dance to while still feeling the sting of those ruined plans and wasted gifts.
Yet tucked beneath the swagger is a lesson in self-worth. After spotting his ex kissing “just a friend” at the club, the singer vows he won’t be fooled again. Sure, she may look perfect on the outside, but another loyal partner like him will be hard to find. The repeated line “Como tú hay otras cien” shows he’s reclaiming confidence, recognizing plenty of options out there—while she, ironically, may never meet someone who loved her as deeply. In the end, “0 SENTIMIENTOS” captures the bittersweet mix of hurt, defiance, and liberation that follows a messy breakup, all delivered with the infectious energy that makes Regional Mexican music so irresistible.
