Finger moustache

From Omnictionary

First used by John Green in his video Nerdfighting in Bangladesh (added 08 April 2008), a Finger Moustache is the act of pointing towards something by putting the index finger under ones nose, much like a moustache. In a Youtube video the Finger Moustache is most commonly used to direct the viewer to the sidebar, which can be found on the right hand side of the video.
