Ayunas literally means "fasting" or "on an empty stomach". It's a word you might associate with medical procedures or religious practices, making its appearance in a hit pop song very surprising and memorable.
In "Hawái", Maluma uses it to recall a specific, intimate memory: "Lo hacíamos en ayunas antes del desayuno" (We'd do it on an empty stomach before breakfast). This unique phrasing paints a vivid picture of a lost daily routine and deep connection, contrasting the polished happiness his ex posts on social media.
Have you ever seen an ex post a picture on Instagram that just screams "I'm over you!"? That's exactly what's happening in Maluma's song "Hawái." The Colombian superstar sings to his ex-girlfriend, who has just posted a photo from a fancy vacation with her new man. He's not buying it for a second. He says, "La foto que subiste con él diciendo que era tu cielo... sé que fue para darme celos" (The photo you posted with him saying he was your heaven... I know it was to make me jealous).
Maluma is completely convinced she's just putting on a show for her followers and, more importantly, for him. He sees right through her perfect Instagram feed, singing, "Muy lindo en Instagram lo que posteas / Pa' que yo vea cómo te va" (What you post on Instagram is very pretty / So I can see how you're doing). He admits her new boyfriend seems like a nice guy, a real "caballero" (gentleman), but insists that she's not truly happy. He believes she's just pretending, because as he says, "el amor no se compra con nada" (love can't be bought with anything).
