I liked it how you repeatedly called him porco dio at the end 
He's not calling him "porco dio" at the end of the song, actually you don't insult people calling them "porco dio".
Porco dio litterally means "god pig ", indicating that god is a dirty/fuking pig, as unjust/unfair/not good and stuff like that...
it's an expression/blasphemy/cursing (bestemmia) (part of informal talking/conversation obviously) used in many different contexts : when somone is angry/happy, to show consense/dissense, it is also used to "reinforce" an action/a partcular charateristic-aspect in a sentence, which is the case in the song made by Djavo, because he says at the end of the song "Unban Panos, porco dio", which translated in English should be something like "Unban Panos, for fuck sake or Fuck, unban Panos or Unban Panos, god damn it" , translating it litterally in English doesn't make much sense "Unban panos, god (dirty) pig" it's just meh...
As i said it can be used in many different contexts, some examples : "God damn/fuck she's such an hottie!" "Porco dio che figa/bella! or che figa/bella porco dio!"
"It's been a long time(since we saw each other)! how are you?" "Porco dio (da) quanto tempo! Come stai?"
You accidentaly hurt yourself/ you are angry about something "porco dioooo!" it can even substitute the " you know, you know" English expression (pet phrase-stock phrase?) "Well you know, it's a matter of reflexes etc..." " (beh) porco dio, è questione di riflessi"
Radament is much more competent than me on this matter .
