Destilan comes from the verb destilar, which means 'to distill'—the process of purifying a liquid. It’s a very poetic and uncommon word to find in a song.
Beele sings, "Esos ojitos amor destilan" (Those little eyes distill love). He's using this word metaphorically to say that her eyes express a pure, concentrated, and powerful form of love, making it a beautiful and memorable line.
Colombian singer Beéle turns stargazing into an obsession in "Estrella Fugaz". He is standing in the ocean at night, begging the sky for a shooting star because he needs proof that this romance will actually happen: "Si el cielo me permite sentir que tú me amas / Quiero volver a ver entre tantas una estrella fugaz" ("If heaven lets me feel that you love me / I want to see, among so many, a shooting star again"). He is not subtle about his wishes, either. The moment he spots that streak of light, he jokes that his wish is to see her naked ("Voy a desear verte desnuda").
Beneath the sweet space metaphors, he keeps his feet firmly on the ground. When he sings "verte me gusta en pila" ("I love seeing you a ton"), he drops a great bit of casual slang: en pila literally means "in a battery" or "in a pile," but here it just means "a whole lot." He also demands honesty before diving in headfirst, saying "las cartas en la mesa están tiras / Habla claro antes de meterle corazón" ("the cards are on the table / Speak clearly before I put my heart into this"). Notice how tiras drops the final "d" from tiradas (thrown)—a classic conversational shortcut you hear all the time across the Caribbean and coastal Colombia. He even pitches his romantic interest like an urban music producer, asking for a "colabo'" (collaboration) with her kisses.
