McFaded is when you're working at McDonald's Zooted off the ZaZa but getting shit donethe right way. It can also mean that you have the Munchies from smoking too much Weed and you make your McFaded ass down to your local McDonald's and order yourself a bunch of food, not hungry you're just Stoned! Enjoy getting McFaded :)
