Jevos is a popular Puerto Rican slang word. It's an informal term for a romantic interest, a fling, or someone you're casually dating.
In the song, Bad Bunny comically sings, “Espero que el perrito los jevos te espante” (I hope the little dog scares your suitors away). He's expressing a mix of jealousy and humor, hoping that his ex's pet will scare off any new guys she brings around. Learning words like jevos is a great way to understand the specific flavor of Caribbean Spanish.
This song is one big, confused question after a breakup. Bad Bunny kicks it off by admitting, "Quizás fui muy ignorante" (Maybe I was very ignorant) and that maybe he didn't do his part. But in the very next line, he points the finger right back at his ex, saying, "Pero tú pusiste menos" (But you did even less). The whole song lives in that messy space. He can't figure out why they split up when the connection was so strong, asking, "Y no sé por qué nos dejamos / Si tú me amas y yo te amo" (And I don't know why we broke up / If you love me and I love you).
He misses the small things, like waking up to kisses, and complains that "Ahora la cama se me hace gigante" (Now the bed feels giant to me). He remembers their dynamic perfectly: he would roll the joints, and she would light them. He even hopes his dog scares away any new guys. It's a mix of genuine sadness and a little bit of ego, especially when he reminds her that whenever she's drunk, she calls him and ends up in his bed wearing his sweater. He knows it's a bad idea, but he can't resist, and he's sure she can't either.
