Plebada is a very common slang word in Mexico for your 'crew,' 'homies,' or 'folks.' It's the plural form of plebe, which informally refers to a young person or commoner.
In the song, the artist kicks things off by addressing his friends directly, saying, "Plebada, ya me perdieron" (My crew, you've lost me), to announce that he's fallen hopelessly in love. It's a fun, authentic word that will instantly make your Spanish sound more native!
Fuerza Regida kicks things off by admitting something most tough guys hate to say out loud: he is hopelessly obsessed. He announces right to his crew, "Plebada, ya me perdieron, me traen enculado" ("Guys, you lost me, she has me whipped"). In regional Mexican slang, plebada refers to the boys or the homies, while enculado is very blunt, explicit street slang for being utterly head-over-heels, hooked, and completely blinded by someone. One kiss was all it took, and now this street-smart narrator is calling her "mi niña hermosa, mi regalo" ("my beautiful girl, my gift").
What makes this track hilarious and entertaining is the clash between sweet romance and a chaotic, dangerous lifestyle. He pulls up to pick her up in cars with heavily tinted windows ("carros bien polarizados"), confusing the neighbors, yet he still wants to be respectful to her family. He drops a funny Spanglish line for her mom: "Dile a tu madre que paso a las diez / No se preocupe, conmigo está safe, suegra" ("Tell your mom I'll swing by at ten / Don't worry, she's safe with me, mother-in-law"). But his version of a date night is wild. He mentions that she loves drinking with him when he's carrying heat ("ando enfierrado"), and if he pulls out his cuerno (short for cuerno de chivo, the street nickname for an AK-47), she is down to shoot it too ("también le gusta jalarlo"). It is an unapologetically wild ride of a love song where meeting the parents meets running the streets.
