A top-notch Karaoke singer who entertains and enthralls crowds with his energetic, tuneful karaoke singing so that he very soon becomes fundamentally inter-twinned with the entire event/night.

Also known and loved for his air-guitarring that drives the ladies WILD!
Dude that baldy rocked the place last night. He is the Ooooma!
