A word invented and popularized in St. Louis that can be used as a both a verb and an interjection. As a verb, shloop is used to describe a motion or an action, such as replacing "run" in the sentance "I will shloop to the grocery store this afternoon," and replacing "skied" in the sentence "I just shlooped down the moutainside for the third time today." As an interjection, shloop is used to exclaim pride and happiness, much like shouting "Yes!" or "Score!" after accomplish a difficult feat like scoring a touchdown or winning a lottery.
