Gomita literally means "little rubber band" and can refer to a hair tie or a gummy candy. However, in Dominican slang, it takes on a much more suggestive meaning.
In this song, Rochy RD uses "gomita" as a double entendre, referring to a woman's thong or underwear. The lyrics like "quítate las gomitas que se te ve igualita" (take off your 'gomitas' because you look the same) play on this slang, making it a memorable and somewhat provocative word in the context of the song.
Rochy RD's "La Gomita" is all about confidence and living life on your own terms, even when others might not approve. He's talking directly to someone who seems to be holding back or trying to fit in, telling them, "quítate las gomitas que se te ve igualita" [take off your little rubber bands, you look the same]. It's like he's saying, stop trying to hide or conform, because your true self is already visible and awesome.
He really hypes up this person, calling them "lo más duro" [the hardest/best] and emphasizing that they're unique. Rochy RD also touches on how superficial some people can be, noting "el economista que tú no tienen plata y siempre vengo vista" [the economist who doesn't have money and I always come into view], pointing out that some people pretend to be something they're not. Ultimately, the song feels like a fun, energetic reminder to embrace who you are and not let anyone dim your shine.
