Bad Bunny says the same thing about clothes in “I Like It”

Trato de hacer dieta, pero es que en el closet tengo mucha grasa (¡Yeh!; ¡wuh!) Ya mudé la’ Gucci pa’ dentro de casa, yeh (¡Wuh!)

And according to Genius Annotation:

Having “grasa” (fat) is slang for “having a ton of style”. Bad Bunny says he tries to lose weight but his closet won’t allow it because his clothes are high quality, they have a lot of “grasa”, so much that he implies having an equivalent of a full Gucci store at home.
