(edit. For the second time this week we are ripping off a popular concept from another website. We acknowledge that. Enjoy.)
Oklahoma is mainly known for petroleum, but the biggest cash cow in this state is frozen water. The technical term for it is "nugget ice," but it can also be called "cubelets" or, according to one website, "rabbit turd ice." Around here, it has only one name: Sonic Ice.
This comes about because Sonic, "America's Drive In" which is based in this state, has become synonymous with producing little tiny pieces of ice that somehow take longer to melt and water down your overpriced soft drink. While this style of frozen water can be acquired in any location that has shelled out for the fancy ice maker, it makes no difference whether the drink was purchased at a Sonic, a gas station, or in your company break room. It is Sonic Ice.
Unlike Xerox, Coke, and Kleenex who have bristled at their brand names becoming the generic term for photocopy, cola, and facial tissue respectively, the Sonic Drive-Ins have benefitted tremendously by having their trademark associated with a product that is apparently as addictive as crack cocaine.
One probably thinks that it is impossible to become addicted to a specific variety of ice. If that is the case, you obviously are not an Oklahoman. Here, people take breaks at work, stop watching the game at home to get in the car, and sometimes even wake up in the middle of the night to get their ice fix.
