Pedo is popular Mexican slang for 'drunk'. It's the key to understanding this song's title, Ya Pedo Quién Sabe, which translates to 'Already Drunk, Who Knows?'.
The lyrics describe a classic dilemma: when the singer is sober, he knows not to call his ex, but he admits that after a few drinks ('ya pedo'), he just might. Learning this word is a great step into the world of informal, everyday Spanish conversation and music.
This song is all about that classic problem: trying to stay away from an ex who was bad for you. When the singer is sober, he's got it all figured out. He tells everyone, "Obvio les digo que no / Que no repito ese error" [Obviously I tell them no / I won't repeat that mistake]. But the minute some tequila gets involved, everything changes. The song's title says it all: "Pero ya pedo quién sabe" [But drunk, who knows?]. Suddenly, he's missing her and thinking about calling.
He knows exactly what caused the breakup, saying his heart was damaged by loving her. The wound is so bad that even a band-aid won't fix it: "La herida nomás no se quita / Ni porque le puse un curita" [The wound just won't go away / Not even because I put a band-aid on it]. He even admits that a previous call was only because he drank some Don Julio tequila! It's a funny and super relatable song about how alcohol can make you forget all the reasons you broke up in the first place.
