sballato perso

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 è sballato perso (that guy is out of order)
non parlare con lui è sballato perso, non ti capisce (don't speak with him, he's out of order, he cannot understand U)
