I could tell by the way she cooked and held her booze that I'd found a McWopper of the highest caliber.

His pale skin, light eyes and curly dark hair made me suspect I'd woken up with a McWopper in my bed. His name...Seamus Calderero, confirmed my suspicions

McMopper

A McMopper is the very awkward mentally retarded person who sweeps up the floors and mops up after obese people leave messes all over McDonalds.

Although a McMopper is usually a nice person who wouldn't hurt a fly with his filthy little hands, he IS very socially awkward, and he insists on making eye contact with everyone, and saying HELLO strangely loud.

The problems that McMoppers cause far overshadow any small good they achieve in a 3 1/2 hour Tard shift at a McDonalds near you. For some people who are highly tolerant McMoppers are not much of a problem, but to the rest of us they are an unnecessary distraction while we stuff our dirty face holes with half rotten beef liver scraps that have been pressed into burger shaped patties and stuffed into a bun with special sauce.

Me: "Fucking Dammit Shit-Covered Dickass I just made eye-contact with that McMopper."

Willy (McMopper): "HELLLLLOWWWW ! ! ! ! !"

ME: "Hey buddy, I'll give you a brand new $5 bill to see how many McNuggets you can fit in your mouth in the middle of the road, and if the cars touch you, you get a sticker!"

Willy: "Okayyyy"
