Contrabsequious 

A word used in contemporary written communications (e.g. texts, emails, and social media posts) written to prove that the receiver of the message is a dumbass who will look up nonsensical words in a futile attempt to seem more intelligent.

Person 1: Did you hear that Weez looked up the word contrabsequious?

Person 2: Did he really? What a dumbass!
