Pop is a carbonated, sweet beverage that one drinks. A toboggan is a big ass wooden thing that you use to go down hills. It's pronounced deh-kal, and black people are identified by their skin colour, not by the prefix "African".

edit: Thought of more (will update as I think of them):
A blood mary is called a caesar.
edit (again): zilla, I just looked at that Harvard site, and while it's interesting to see which way the majority of the population pronounces certain words, it seems that the distribution is primarily just a display of the total distribution of the United States' population (primarily on the East Coast (especially the North East) and coastal California).
