If you live in New England, a frappe is a delicious, creamy, frozen drink — in other words, it's a milkshake. Order a frappe at a diner in Idaho, however, and you'll probably get a confused look.
The meaning of the word frappe varies depending on what part of the world you're in. In Massachusetts or Maine, ordering a chocolate frappe will result in a milkshake: ice cream that's blended with syrup and sometimes milk which you can sip through a straw. In other areas, a frappe is a frozen coffee drink, a variation on fruity shaved ice, or even a crispy pastry. The French source is frappé, "made cold with ice."
