The boyfriend that everybody hears about, but nobody sees. He has a wife, so he doesn't like to be known as your boyfriend by anyone other than you, but calls you his girlfriend. You are his secret lover.
My invisible boyfriend came over today, but he left before anyone came home.
Your majesty and your highness made into one word. When you act like your royalty, but your really not. Someone who thinks their "shit don't stink".
Call me Your Highnesty, I know everything and you know nothing!
