McDuffy 

The part of your golf game that is giving you the most problems or the mental part of the game that you need to get over in order to get to the next level.

Using my driver to hit the ball far and straight is my McDuffy in golf!!

McDuffle Shuffle 

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?

It means he is Crazier than a rathouse shit.

Banana McDuffie 

A mixed drink made up of a whole banana that is soaked in a large glass filled with vodka, rum, whiskey, hpnotiq, tequila, and gin. Once the banana is thoroughly soaked, you eat it as quickly as possible and wash it down with the mixture of alcohol remaining.

Guy 1 - "I went to the craziest party last night and saw this guy make and eat a Banana McDuffie"

Mcduff 

When a person runs up to a person with a broken bone and happily punches/hits them in that spot without realizing it. Also dosen't apoligize afterwards and plays off the experience.

Cripple: that kid just f***ing mcduffed me it hurt like hell.
Observer: he atleast apoligized right?
Cripple: no he just left... What kind of a person does that?

J.D McDuffie 

Longtime NASCAR independent campaigner J.D. McDuffie was bucking heavy odds by 1991. With corporate sponsorship financing most of the teams, McDuffie's homespun operation was only able to qualify for a few NASCAR Winston Cup events. McDuffie attempted to qualify 14 times in '91, but only made the field for five events. In the Aug. 11 race on the Watkins Glen road course, McDuffie lost a wheel and slammed into a retaining barrier. Tragically, he died in the acceident. McDuffie competed in races from 1963 to 1991, logging 106 top-10 finishes, but no wins. In October 1998, NASCAR driver Bobby Hillin, Jr. swore he saw the ghost of McDuffie standing in the very spot where his car hit the retaining berriers, while Hillin was in a testing session on the course. Though nobody believed him.

"J.D McDuffie has over 650 starts in the NASCAR Nextel Cup Series."
