One of the most obvious differences in dialect is what we call carbonated beverages. I call it Coke. (And if you call it Pop, you're obviously wrong.) The first time I heard it called Pop, I thought they were talking about a lollipop. (Which is apparently called a lolly in some places?!)

When I meet people from the far reaches of America (read: the Pacific NW, New Yorkers, Celtics Fans), I bombard them with dialect questions. "What do you call the thing you push around the supermarket?" "What do you call your parent's sister?" "How do you say the maple sauce you put on pancakes?" "How do you address a group of people?"
Is the sandwich Sub or a Hoagie? Do you toilet paper a house, or roll it? Is it a Rolly Polly bug, or a Potato Bug? Tennis Shoes or Sneakers? Is the spider called a Daddy Long Legs or a Granddaddy Long Legs? Do you grocery shop with a Shopping Cart or a Buggy? Do you change the channel with the remote or the clicker?
My answers are the first in the question. What do you all say?
