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 communist 

A person who tells you better, more complicated words you could have used in your previous sentence. Often a grammar nazi as well. Always annoying.

Person 1: "Dude, that was totally not needed!"

Person 2: "I think you should have said 'that was totally superfluous'."

Person 2: "Stop being such a vocabulary communist."
