A horribly misspelled word from a friend who has never heard of the concept of a spell checker. Meaning: Coincidence.

(Even when he's on his 'Mac' he can't spell even though it's built-in. This is why Mac users fail. :D)
Person 1: "((Physics Questions)) actually never did post them, just stumbled upon it realizing it was the same questions xD"

Person 2: "Wow huge quadinvadence"

Person 1: "quadinvadence.... is that even a word? xD 'coincidence'?"

Person 2: "That's the one!"
