A double double is Canadian slang for two cream or milk and two sugars or sweeteners in a coffee typically Tim Hortons (Canada's equivalent to a Dunkin' Donuts) . If you do try anymore Canadian treats I would recommend fuzzy peaches if you like peach or gummy candles, thrills gum just to experience it, Aero, Crunchie (Cadbury) and hickory sticks. As for the all dressed chips they are supposed to be bbq, ketchup, salt add vinegar and sour cream and onion.
Ok so for everyone who might ask, in the 90's ruffles/lays had a contest to pick a new flavour, all dressed won, and it is a combination of the most popular flavours at the time, ketchup bbq, salt and vinegar and sour cream and onion
