The legendary goop from which all McDonald's menu items are derived. Chilled and pooped out of machine into a cup, it's a shake. Baked in an oven, it's a bun. Grilled, it's a burger. Molded different ways and fried, it's french fries, chicken nuggets, onion rings, etc.

Generally anything that comes from a McDonald's restaurant.

Also anything that's cheap, abundant, undesirable and valueless.
The McStuff... it is... ALIVE!
