This one is a breakup that falls apart in the funniest way. She had him blocked on her phone ("bloqueado me tenías del cel" [you had me blocked on your phone]), and he admits he only called because "unos tequilas que los huevos me activaron" [a few tequilas got my nerve going]. In Mexican slang los huevos here means guts or nerve, so the tequila did the talking.
Then comes the title line: "Y tres Doritos después" [and three Doritos later]. It is a goofy way of saying "not long after", and a second later "ya los vidrios empañados" [the windows are already fogged up]. You can guess what happened in that car. The chorus keeps it sweet though: "Nos queremos, nos amamos" [we love each other] and a plan to "manejar por la ciudad" [drive around the city] at night.
Panter Bélico's verse adds a warning. He is "tu chofer, tu amigo y también tu cajero" [your driver, your friend and also your cashier], but "si la cagas de nuevo" [if you screw it up again], this time he won't forgive her. Recorded live in Hermosillo, Sonora, you can hear the band and the shout-outs between the two singers, which make it feel like a party rather than a studio track.
