It comes from Italian slang and it literally means "dead of pussy". It can be referred to any man who had never kissed a girl or had sex in ages and absolutely needs a girl and therefore sees every girl beautiful and attractive even if she's the ugliest. Everything he hears, he percives it as something that has to do with sex, his vocabulary is very short, he often watched porn movies and would do anything even to just see a pair of boobs. He hardly succeeds, though.
