Diabla literally translates to "she-devil". This word is often used in Latin music not as an insult, but as a term of endearment for a woman who is wild, passionate, and irresistibly seductive.
In "Regresa Mami", the artist sings "Mi cama te extraña tú cuerpo de diabla" (My bed misses your she-devil body). He uses this evocative word to reminisce about his ex-lover's fiery personality and the intense passion they shared.
In "Regresa Mami", Eslabón Armado is stuck indoors on a cloudy day, feeling trapped while obsessing over an ex. The song cuts straight to the point: he is lonely and looking back at the wildest times they shared together. He brings up beach dates, endless nights, and flashier scenes like renting a boat in Miami with "botellas de Ace" (bottles of Armand de Brignac Champagne, often nicknamed Ace of Spades). He even mixes English slang into his Spanish lyrics to describe their former bond, declaring "Éramos un team" (We were a team).
The lyrics bounce between genuine sadness and shameless nostalgia. One moment he is staring at old photos and videos feeling miserable ("Y ahora me encuentro infeliz" [And now I find myself unhappy]), and the next he is remembering her dancing without a care in the world ("Perrea sin permiso" [She perreos / dances reggaeton without asking for permission]). It is a direct, nostalgic plea for her to come back, fueled by great memories, luxury drinks, and lingering romance.
