The "Confusion Stutter" happens when two people are walking in opposite directions in presumably the same line of travel. Each person does an awkward stutter step trying to find a way out of this predicament. This can repeat several times until they gather a small, yet rowdy audience who hope to see the persons involved collide in what is known as the Confusion Stutter Collision. The involved people may smile and laugh awkwardly with inept hand motions in the decision making process of which way to go, and if they cannot, it ultimately results in the Confusion Stutter Collision, which is just plain embarrassing.
Man, I saw the best Confusion Stutter show today, these two dorklings couldn't find a way around each other and I literally saw the awesome Confusion Stutter Collision.
