A stage troller is a singer or musician who hangs off to the side, or makes passes across the front of the stage area, while other bands are playing. They do this in hopes of being asked up to make a “guest appearance”.

This is a common behavior where the person can be content to being a spectator, but has to show everyone in attendance that he/she is a “star” too. They will usually overstay their welcome if asked to join the band for a song, and their presence becomes awkward.
Man, did you see Geoff last night, making his rounds on the dance floor in front of the band? He’s such a stage troller!

The show was going great last night until the band invited a stage troller up for a song and he wouldn’t leave!
