Baba literally translates to "drool" or "slime." It's an unusual and somewhat visceral word to find in a song, making it quite memorable.
In the lyrics, the phrase "Y trazo un circulo de baba" (And he drew a circle of drool) creates a bizarre and intriguing image. It suggests a desperate, almost primal act, hinting at the character's descent into madness or a strange ritualistic behavior after a heartbreak. This unexpected use of a common bodily fluid in such a context makes it particularly striking.
This song is a wild ride into a twisted love story, or maybe a story about obsession and its dark consequences. We meet Sasha, who's clearly in a bad place, thinking about how he saw someone who "no dijo nada" [didn't say anything] and how he loved "su divina Sissí" [his divine Sissí] so much. It sounds like Sissí really messed with him, as the lyrics say "Sissi lo volvió loco en una fiesta" [Sissi drove him crazy at a party] and then "no volvió a tocarlo nunca más" [never touched him again].
Sasha's feelings spiral from wanting to kill her and run away to writing a requiem for them both. Then, in a really strange turn, he waits for her, kisses her, and when she arrives, he sleeps. He even draws "un circulo de baba / Con un medical style" [a circle of drool / With a medical style] around her, making sure "no dejo que nunca más sufriera" [he never let her suffer again]. But the twist is, "Sissí murió de hambre y vanidad" [Sissí died of hunger and vanity]. It's a pretty dark and surreal look at love, control, and what happens when things go really wrong.
