Yeah, there is a subset of guys (never seen a female with these tendencies) who swing their arms in a four foot long arc while taking about two foot long shuffle steps with their feet. They would knock you out cold if they ever connected with the arm swing but you can hear them coming from fifty yards away with the foot shuffles and always have time to get out of the way by the time they actually get to you. Kind of a Neanderthal version of a rattlesnake rattle.
