Another popular local name is Mudbug.
I grew up drinking Pop. Moved to South Arkansas and it was Soda Water. Moved to Louisiana and it's Coke, no matter what brand it is. In various parts of the U.S. I've heard it called Soda, Cola, and Soda Pop. It's all the same, Crawfish, Crawdads, Mudbugs, Crawfish. But if you call it by the wrong name in the wrong place people will know you're a Yankee!
