Encamado literally means 'bedridden' or 'confined to bed'. However, in Mexican slang, it can also imply being pampered or spoiled, especially in a romantic context.
In this song, the singer laments, "Me tenías tan encamado, me consentías como niño" (You had me so pampered, you spoiled me like a child). This dual meaning makes the word interesting, as it conveys both a sense of being completely taken care of and perhaps a touch of helplessness or dependence on the lost love.
El Komander's "Malditas Ganas (Banda)" is all about that intense, almost desperate feeling of missing someone after a breakup. Our singer is really going through it, trying to drown his sorrows and forget his ex. He's got his cooler full of beer, his iPhone blasting music, and he's just thinking, "Desde que te perdí, ando piense piense piense en tu cariño" [Ever since I lost you, I've been thinking, thinking, thinking about your love]. He admits he was so used to her, saying, "Me tenías tan encamado, me consentías como niño" [You had me so spoiled, you pampered me like a child].
He's got these "ganas horribles de llamarte" [horrible urges to call you] and even drives by her house, battling the urge to stop. He knows he should probably forget her, but he just can't, especially because she's so beautiful: "Si no estuvieras tan chula te olvidaba" [If you weren't so beautiful, I'd forget you]. He even brings a serenade to her house, hoping she'll come out, playing her favorite songs. The song ends with him still unable to let go, confessing, "No sé qué chingaos me diste, pero olvidarte no puedo" [I don't know what the hell you gave me, but I can't forget you]. It's a pretty relatable story of heartbreak and just not being able to move on.
