vocabulary hijacking 

Choosing a word because it evokes a specific emotion rather than because it is accurate.

After 9/11 the word "terrorism" became a much more emotional term for Americans than before, when it was equally deplorable yet much more theoretical in most people's minds (i.e. something that happens elsewhere). Consequently, politically active people engaged in vocabulary hijacking by applying the term "terrorist" to their opponent's activities (e.g. environmental "terrorists", government-sponsored "terrorists", anti-choice "terrorists").

prison vocabulary 

A vocabulary that includes obscure polysyllabic words that are often used incorrectly and/or out of their proper context. Specifically with people who don’t have the elloquence or articulate speech to match it.
Named so, because it was first observed with Mike Tyson after he finished a prison sentence for rape. One could imagine him sitting in his jail cell with nothing to do but read his dictionary.

From Tv: Lennox Lewis, I'm coming for you man. My style is impetuous. My defense is impregnable, and I'm just ferocious. I want your heart. I want to eat his children. Praise be to Allah!"

Martha: Did he just use the words impetuous and Impregnable
Lucius: Thats his prison vocabulary

Vocabulary.com 

A terrible website which naive teachers use which allows you to create a list of vocabulary to study and quiz yourself over. It will allow you to "master" all but one of the words, then force you to sit through hours of questions you already know the answers to so that you can finally answer the last question about the last word so that you can "master" it.

I stayed up until 2:00 AM mastering all the vocabulary for homework. Fuck vocabulary.com for wasting my time on words I already know.

Vocabulary Nazi 

A person who purposely uses large words, and speaks very articulate, as a way to out show the people within his surroundings. Usually thinks they're better than everyone else because they use large words that no one has ever heard of. The words are usually learned from their vocabulary book in high school.

Bjorn: "The premise of the antithesis of the conjugation of the multiple sub-components is invalid."
Bjorn's friend: "Bjorn, what the hell are you talking about?! Quit being such a vocabulary nazi!"
