The word has a distinct feel, and power to it. To yeet is to give your full power and soul to an action you're doing. While many believe yeet to be a fairly new concept, it has been around for centuries. Think back to the berserker warriors. They would be so immersed in pushing all their power into their attack that they wouldn't even register pain, or go into shock, until long after a regular fighter would have passed out. They were true yeeters. A more modern example is the common use of warp speed in science fiction. It's interstellar yeet. The word 'yeet' is really all that is new about this concept, and it is a very useful word indeed.
