Here in Texas, all soft drinks are Coke. If you sit down at a table and the waitress asks what you want to to drink (tea, water, Coke), you say Coke, she'll then ask what kind. I noticed it years ago that people from other states would get flustered at that point. It was just common place to me to order a Coke and then specify a Mountain Dew.
All ramen noodles are simply ramen noodles.
All "weed whackers" are weed eaters.
