'50s version of what dude is now. Today it is barely known and lies almost completely forgotten amongst all the other odd words thought up, used and then thrown away and only used by weird people that can't let go.

D'Addio is an amazing, perfect last name. It comes from North of Naples, Italy, and it has somehow made its way to America through a long line of family members. Everyone wishes they could have this last name.
Oh, I wish my last name was as cool as the D'Addio's.

The D'Addios are the coolest family around!!!

Person trying to be the coolest human alive but screws any and everyone over to get there. Uses people as tools to make oneself appear cooler than they are. Term only used with respect by children who don't know the truth of a Daddios true character.
That daddio would be nothing but a loser if they didn't have people they could manipulate, use and step on. At least daddios kids don't know what daddio has done or they wouldn't respect that POS daddio either.
(Least daddio has them fooled... For now)
