A condition when a person's act becomes tedious, stale, monotonous and boring. As a result, no one will pay attention to him anymore. Much like the dog who wagged his tail so much that it fell off!
"Valkyre" would have been a great movie if that wagged out Scientologist hadn't played the main role!
Travolta is so wagged out on Dianetics that he played "Edna" in the remake of "Hairspray."
Jerry Lewis should have retired before he wagged out on us.
The 10 out of 10 on the drunk scale. What is this? Getting so drunk you actually have to be brought back from life. If you please you can get so drunk at a football that you tackle a fire hydrant, puke on every inch of a bathroom stall: except in the toilet.
