Scarface Delusion
The strange and sad phenomena that every currently or formerly drug-addled chav, wankster, or kid in treatment/NA that ever sold a couple of dubs of schwag to his buddies seems to be affected by; that he was some major drug dealer or big player in the game of his (usually hick) town.
My kid brother seems to think that because he sold a few of his classmates some of his ritalin he's now Tony Montana. He's obviously suffering from the Scarface Delusion.
