A person who stands on the sidewalk or street corner dressed as Uncle Sam, Lady Liberty or of the like. Their intention is to rope you into impulsively stopping at a close by Tax Filing business. Tactics include; Dancing, jumping up and down, or waving a sign, foam finger, pool noodle or any other annoying thing they can think of.
Driving to work I almost rear ended someone at the light because I was distracted by this Taxdancer. Although... he did have a rather good air guitar technique.
