Borondo is a cool and very specific Colombian slang word for going on a stroll, wandering around, or partying. You definitely won't find this one in a textbook!
In the song, Beéle sings that he hopes the girl makes him settle down "del borondo" (from the wandering/partying). He's saying he's ready to trade his carefree, party-boy lifestyle for her love, which is a pretty romantic and modern declaration.
Ever been told not to fall for someone, but your heart just laughs in your face? That's exactly what's happening to Colombian singer Beéle in this track. His friends and even his mom warn him, "No te vayas a enamorar" [Don't fall in love], but he sees a woman who is just too amazing to resist. He calls her "Top diesel, top de cara, top princess" [Top quality, top face, top princess], basically saying she's the absolute best in every way.
He knows he's in trouble. He tries to tell his heart to behave, but it's no use. He admits, "Yo no sé decir que no" [I don't know how to say no]. His imagination runs wild with hilarious and over-the-top thoughts, from wanting to meet her mom to hoping love makes him gain weight so his aunt will notice. He's completely losing his cool over this girl, and he's ready to ignore all the warnings and dive right in.
