noun- Used in reference to any type of machinery or gadget, either very complicated or with no discernable purpose. Made famous by MAD Magazine. Believed to have originated from a combination of Yiddish words, "webel," meaning weaving, and the German "Fetzer" which could mean any type of contraption.
"Good morning, Ma'am! May I interest you in purchasing a Left-Handed Veeblefetzer?"
"I'm not sure... what exactly does it do?"
"Why, it fetzes left-handed Veebles, of course!"
