Air Sex - No comment!

Air Sex is a performance activity invented in Japan; clothed men and women simulate sexual activity with an invisible partner, often in an exaggerated manner, set to music, and in a competition before an audience. This is somewhat akin to playing air guitar, explaining the name. The creator, J-Taro Sugisaku, says that it was invented in Tokyo in 2006 by a group of bored men without girlfriends.
