that's an italian way to call someone which is really high, and for this reason he's Out-of-order like a videogame broken. It's a slang which has been extended to all kind of drugs.
quello li รจ sballato perso (that guy is out of order)
non parlare con lui รจ sballato perso, non ti capisce (don't speak with him, he's out of order, he cannot understand U)
