"Aspanterasloucodesejodasobrinhaavi" – maybe this is a misspelled or a creative spelling of a Portuguese phrase. Let me try to parse each part. "Aspanteras" could be a name or a misspelling. "Louco" in Portuguese means "crazy". "Dessejo" or "desejo" is "desire". "Da sobrinha avi" – "sobrinha" means "niece", "avi" might be "avi (aviation)" or a nickname. Or maybe "avi" is a name. Putting it together, maybe it's "Aspanteras, o louco desejo da sobrinha avi", which would translate roughly to "Aspanteras, the crazy desire of niece Avi".
