The McDuffle Shuffle can be seen almost exclusively on the west side of Jacksonville Florida on McDuff Ave. The McDuffle Shuffle consists of standing on the corner with an incomprehensible sign, often attached to a tennis racket. A shuffler is often mistaken for a bum, but bums carry signs that make more sense.
A true Shuffler often offers extremely good song lyrics for sale (mostly rhyming) and plasters his windows with various batshit crazy rants.
Hey look at Jeff, he is down on the corner doin' the McDuffle Shuffle again.
Yup, he sure is, look at his sign, it says, "Munchausen by Jackass" what the fuck does that mean?
Kage: "Now that McDonalds is serving breakfast all day, I'm going to go in around 12:30 get an egg mcmuffin and put it inside the double cheeseburger and make a mcmuffbang!"
Fisher: "Are you serious? You need to trademark that."
Kage "I just did! Its like a mcgangbang when you combine a mcchicken and a double cheeseburger."
Fisher: "I only wish I could come up with as amazing ideas as you do Kage."
