Fatboy Swap 

When you and another person order two different sandwiches and trade halves, giving both eaters the best of both worlds or simple variety. This can be done with other meals/food but a true Fatboy Swap is done with sandwiches.

Invented circa 2011 in Chelsea Market by Michael Hoey

Damn Big Ciel, I can't decide between the prosciutto or the sausage with broccoli rabe...Fatboy Swap?

fatboy slim 

One of the best musicians today. If you haven't heard of him, you don't know what music is. And anyone who says he sucks is an MTV-brainwashed faggot.

I just got 2 of Fatboy Slim's CDs on discount, and that was the best $15 I ever spent. Pure musical bliss. :^D

Fatboy 

A overly thin white boy that can easily eat 10x as much as anyone, and yet, not pack on a single pound. Moreover, he will continue to pull things out to eat after a meal has been served. (fatboy, fatboyish, fatboying, fatboyed)

"Holy shit, look at fatboy go, he just finished off that bag of Oreos, and now he's making four bags of instant Maple Brown Sugar Oatmeal!"

"Hope you got some food back at your place, I'm feeling fatboyish!"

"After I smoked last night, I fatboyed three cans of Pringles!"

Cuban Fatboy 

An enormous, solid bowl movement that settles in the toilet pan without breaking thus resembling a huge Cuban cigar.

Archibald: Wow, do I feel better now!

Cyril: Why so old chap?

Archibald: I just curled out the most monstrous Cuban fatboy you've ever seen. The tip was poking out of the water it was so big!

Cyril: Huzzah!

Archibald: Huzzah!
