The act of putting your flaccid penis in an Dyson Airblade hand dryer, and let it flop around in the hot air.

The phenomenon was first described by a Norwegian comedian in late 2012, and the phrase was later coined by another Norwegian comedian in early 2016.
I really wish I owned a Dyson Airblade, so I could perform the flying dyson daily.
