A unique weapon of grammar combining words in a fashion similar to a contraction, but with three words and two apostrophes instead of two and one, respectively. Usually used by people who are too important to speak with any normal regard for english.
"I wouldn't've used a double contraction."
"I'd've told you about double contractions, but I would have had to kill you."
"I'd've told you about double contractions, but I would have had to kill you."
