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?
