The Fallacy of Prestigious Jargon
From Great Debate Community Wiki
The Fallacy of Prestigious Jargon (aka "egregia tum dicta") is TrueEmpiricism's belief that using technical words properly in a conversation by someone is a fallacy and should be avoided at all costs. He does not outright say it, but he seems to maintain that people should use the most ambiguous, colloquial definitions possible... else it's a fallacy.
