How did you dovelop Oklahomas nikename?

Answer 1

Are you referring to Oklahoma being called the "Sooner State?" The name came about when they had the landrun. The people who crossed the line before the gun sounded were called Sooners. The people who waited till the gun sounded were called Boomers. Thus the nickname of the state and the reason the University of Oklahoma teams are called the Boomer Sooners.
