A delicious "hot n spicy McChicken" inserted inside of a double cheeseburger (bun and all). Complimented well by a value menu "dollar fry". All found at your nearest McDonald's.
Ryan: Hey Henry! How about a McChubby for Dinner?
Henry: I don't know man, i heard it tasted really good, but it was really expensive.
Spenser: Who did you hear that from?! It's only $2.18!!
Henry: A Double cheeseburger and a Hot n Spicy in one for half the price?! I'm Down

The hankering you get when you want McDonalds' food, often be associated with the "munchies" but only when the hunger is for the golden aches' menu.
Can be spelled "McChubbys" in some circles.
Person 1: "What are you feeling for dinner tonight?"
Person 2:"I've got the McChubbies, lets go to McDonalds."

.....

Person I: "I am so hungry after hitting that pipe, I've got major munchies."
Person II: "Yeah same, let's go to McDonalds, I've got the McChubbies."
