Peda is a very common slang term in Mexico for a drunken party, or more generally, the state of being drunk. The song's title, 'Cosas De La Peda', translates to 'Things That Happen When You're Drunk'.
In the song, the artists sing about the regrettable (and relatable) things people do under the influence, like texting an ex. Learning slang like peda is a great way to understand informal conversations and the real-life culture behind the language.
Ever received a text from an ex after months of silence and instantly spiraled? That is the exact mess Prince Royce and Gabito Ballesteros walk into in "Cosas De La Peda". The title uses the Mexican slang peda, which means a drinking binge or party. Royce starts by admitting that getting a simple "Feliz cumpleaños" ("Happy birthday") completely wrecked his progress. Instead of lying about moving on, he confesses: "Te extraño, pero borracho no me duele tanto / Por eso es que tomo hasta cuando me levanto" ("I miss you, but drunk it doesn't hurt so much / That's why I drink even when I wake up"). He even begs God that she never texts again, because he knows he lacks the willpower to say no if she asks him back.
Gabito jumps in to deliver the other side of the story, calling out the ex for her own drunken antics. He pictures her "bailando las de Selena" ("dancing to Selena's songs") and pretending she is doing fine, yet blowing up his phone with wild mood swings: "Que me paso de cabrón, después, 'Te extraño, mi amor'" ("That I'm a complete jerk, and then, 'I miss you, my love'"). He also throws in cheeky pop culture nods, like joking that he'd be the unluckiest man "si fuera con Laura" (referencing the chaotic talk show Laura en América) and telling her not to dedicate Karol G's hit "MI EX TENÍA RAZÓN" ("My Ex Was Right") to him because it just doesn't fit. It is a delightfully honest bachata track about using alcohol as a shield against bad romantic decisions.
