Picapica refers to a classic novelty prank: itching powder, a substance that causes intense itching when it touches the skin. It's a very specific and playful word rarely found in everyday vocabulary, let alone in songs.
In this vengeful 80s hit, Hombres G uses the word in the darkly comedic threat "Voy a llenarle el cuello de polvos picapica" (I'm going to fill his neck with itching powder). The repetition of this quirky, child-like word in a rock song about heartbreak and revenge makes it incredibly memorable and shows a unique, humorous take on jealousy.
Talk about messy breakups! In "Devuélveme A Mi Chica", Spanish band Hombres G skips quiet grief and heads straight for ridiculous, over-the-top revenge. The narrator kicks things off weeping in his bedroom ("Estoy llorando en mi habitación" [I am crying in my room]) because his ex left him for a "niño pijo" ("Ella se fue con un niño pijo" [She left with a posh boy / preppy rich kid]). In Spain, pijo refers to a wealthy, spoiled snob, and this rival fits the bill perfectly: he drives a white Ford Fiesta ("Tiene un ford fiesta blanco") and sports a bright yellow sweater ("un jersey amarillo").
Watching the new couple make out in the park is pure agony ("Cuando se besan lo paso fatal" [When they kiss I have a terrible time]), so our petty protagonist plots his payback. Forget mature conversations; he decides to pour itch powder down the guy's neck: "Voy a llenarle el cuello de polvos picapica" (I'm going to fill his neck with itching powder). Burning the rival's sweater totally backfired because the rich guy simply bought half a dozen replacements ("Se ha comprado cinco o seis"), so now he plans to trash his car tonight ("Voy a destrozarle el coche"). The ridiculously catchy chorus chants "Sufre, mamón, devuélveme a mi chica" (Suffer, jerk, give me my girl back), tossing around mamón (a blunt insult meaning 'sucker' or 'jerk') while swearing the girl will come back someday. It is dramatic, petty, and wildly fun to sing along to.
