This word is derived from the word "waiter" or "waitress", and put together with the suffix "-tron".
Etymology of "-tron": Greek, suffix denoting an instrument; akin to Old English.
It is a dehumanizing term often used to refer to a waiter/waitress.
Dick goes into a restaurant and places a stack of one dollar bills on the table. Dick tells the waitron that this is his tip. If the waitron does bad, a dollar will be taken away. Good, a dollar put back. As his server slowly dissatisfies him, he removes the money from the tip pile. Waitron is saddened.
A figurative term to describe a bad pass. "Wounded duck" passes either have no chance for reception by an offensive receiver due to any number of poor dynamics on the thrown ball, or simply should be intercepted by the defense for being so poorly thrown.
So Ben Roethlisberger was a mess yesterday, looking more like a modern-day Cliff Stoudt than the guy who led the Steelers to a win in Super Bowl XL. Benjamin floated three wounded ducks into the waiting arms of Colts defenders at critical times yesterday, outright costing the Steelers the game.
