Gonorrea literally refers to the sexually transmitted infection gonorrhea. However, in Colombian slang, it's used as an interjection, similar to 'damn,' 'asshole,' or 'motherf***er,' to express frustration, surprise, or emphasis.
In the context of the song, the artist says, "Echa gonorrea, tomándome este vinito, pa'" (Damn, taking this little wine, for...). It's a raw and authentic expression of emotion, reflecting a moment of reflection or perhaps slight regret while reminiscing over past memories. This word is highly characteristic of Colombian street slang and offers a glimpse into a more informal, regional use of Spanish.
"Palabras Sobran" ("Words Are Unnecessary") is Blessd's take on a love he can't shake. He keeps replaying a memory of one night together, admitting he can't stop thinking about her kisses, her eyes, the whole scene.
Most of the song is him trying to convince her (and maybe himself) that he wants her fully, not just for a little while. He owns up to falling for her without meaning to, and apologizes for how intense that's made him.
The title lands in the final line: after all the wanting and remembering, he decides that talking about it is pointless. Between them, words are unnecessary.
