What is a double double?

A "double double" can refer to a few things, most commonly:

• InTim Hortons (and similar Canadian coffee shops): This refers to a coffee order: two sugars and two creams. It's become a cultural phenomenon in Canada, shorthand for a specific type of coffee and a widely understood term.

• In some other contexts (less common): It could refer to anything with a double quantity of two things. For example, a "double double cheeseburger" might have two patties and two slices of cheese. However, without the specific context of a Canadian coffee shop, this interpretation is far less likely.

Therefore, unless specified otherwise, when someone says "double double," particularly in a Canadian context, they are almost certainly referring to the coffee order from Tim Hortons.
