Embicha' is a Puerto Rican slang term, a shortened form of "embichada," which means to be under the influence of drugs or alcohol, or generally in a wild, uninhibited state.
In the song, it's used to describe a group of women: "Se junta con su corillo, to'itas embicha'" (She hangs out with her crew, all of them high/intoxicated). This word is interesting because it's a regional slang term that captures the rebellious and party-hardy attitude of the characters in the song, making it unique and memorable.
KEVVO's "R Sport" is all about a woman who's completely independent and living life on her own terms. She's got style, always dressed in boutique clothes, and she's a bit of a wild card, described as "problemática como una forty con chip" [problematic like a forty with a chip].
She's definitely not looking for love, having "mató el amor" [killed love] and saying she has a blast being single. When she drinks, she gets "peligrosa como una R Sport" [dangerous like an R Sport]. She's got her life figured out, doesn't trust easily, and has left love "on hold." The singer is clearly smitten, though, even saying, "Yo te quiero en mi cama como mi desayuno" [I want you in my bed like my breakfast]! It's a fun, energetic track about a woman who is confident, self-sufficient, and a little bit dangerous.
