The male version of the fine art of shadowdancing. Usually on lit up boxes, in clubs that rock the techno music. Straight men are usually tanked to do this, while the lighter in the feet do it gleefully.
Dude I got so tossed last night, I got up on the box and shadowmanced.
I am so good at shadowmacing that I need a tee-shirt that declares me "SHADOWMANCER".
I totally met a hot guy shadowmancing last night, too bad he turned into a walk of shame.
