The little dance you do when trying to avoid someone walking towards you, and you both end up side stepping about three times into each others way before laughing awkwardly and you or your dance-off opponent lets you pass.
I was walking through town today and did the sidewalk boogie with about five people.
That awkward left to right dance you experience with a random person walking on the same side of the sidewalk as you.
You are walking along the sidewalk and someone is walking towards you on the same side. Eventually one of you has to move out of the way but you move to your right, the other person moves the same way, you move to your left, the person moves the same way and you both do a SidewalkBoogie dance until someone stops and lets one person walk by.
