Someone who can be a very big criminal and/or may be wearing a hat, typically either a beanie or fedora. Often the head of a crime ring (Or multiple crime rings), similar to someone with the alias "Big Tony" or "Frank Sinatra". Will insist on being referred to as "The Big Cheese" rather than their actual name, even when talking with friends. Will have an odor of feta, cheddar, gouda, blue cheese, swiss, provelone, brie, American?, pepper jack, parmesan, or gerbils, but only one at a time. The true name of someone with "The Big Cheese" as their alias is often concealed, but have often been found to have stupid names that are one syllable and contain four letters.

The Big Cheese: I'm going to have my underling Smooth Jimbo rub you out for that comment, you sack of overused marmalade. Then I'll put so many holes in you that you'll look like that piece of Swiss Cheese I slammed down my gullet this morning.

The big cheese is the person who holds the most power in any situation. If you overhear someone at work describe you as "the big cheese," it means that he thinks of you as the most important person in the office.
