La Estaca by Aterciopelados is a love song written entirely in insults, and it is very funny. It opens like a classic serenade, "Tus ojos son dos luceros" (Your eyes are two bright stars), and then swerves: they are stars "Que alumbran los basureros" (That light up the garbage dumps). Every compliment gets flipped the same way. The legs are "dos estacas" (two stakes) "Para amarrar muchas vacas" (For tying up lots of cows), the hair is "como un trapero" (like a mop), "Enredado, sucio y feo" (Tangled, dirty and ugly). Using patas (animal legs, paws) instead of piernas for a person is already a jab.
The chorus is a cheerful goodbye packed with curses: "Adiós, que te vaya bien" (Goodbye, I hope it goes well for you), then "Que te coja un carro" (May a car hit you), "Que te parta un rayo" (May lightning split you) and "Que te lleve el diablo" (May the devil take you). Que te parta un rayo is a real everyday Spanish curse, so this one is worth learning. The twist comes at the very end: after "Tú no eres más que un salvaje" (You're nothing but a savage), the singer admits "Y yo te quiero a morir" (And I love you to death). All that abuse was a crush in disguise. Grammar tip: every que te... line uses the subjunctive to wish something on someone.
