Garrobero is a distinctive regional word connected to the garrobo, a large Central American lizard similar to an iguana. In the song, it humorously describes someone who eats plenty of garrobo, giving the repeated chorus its memorable, playful character.
In “El Garrobero,” Aniceto Molina jokes about a boy whose mother says he is Aniceto’s son. The singer wants an ADN test, or DNA test, to settle the question. If the boy really is his, he gives him a very specific list of qualities: “Quiero que toque acordeón, así como su papa” [I want him to play accordion, like his father], be mujeriego [a womanizer] like his father, but not drink rum, and be “bueno y bien sincero” [good and very honest]. The combination is funny because the father wants to pass on both his musical talent and his questionable reputation, while leaving out the rum.
The song then turns into a playful travel-and-food fantasy. The boy should go to El Salvador, eat mariscada [a seafood dish], Pollo Campero, cusuco, and plenty of garrobo, a Central American reptile often eaten as food. Eating garrobo is what gives the boy the nickname “El Garrobero,” repeated like a chant. The line “Pa’ que sea un buen semental” [so he will be a good stud] pushes the joke even further, while the repeated “así como su papa” [just like his father] keeps the whole song focused on exaggerated family resemblance. If the DNA test says the boy is not his, the singer throws in another teasing punchline about him being “de chungo grande,” then ends with playful shouted names and laughter.
