7:2 Miscreant

When and Where I Found It:  I was watching an old episode of Gilmore Girls.  At one point in the episode, Rory called Logan a "miscreant" because she was angry at him.  

What It Means:   According to dictionary.com, miscreant is a noun (in this case) that means "a vicious or depraved person; villain."  Rory was so angry with Logan for playing a prank on her in class that she called him a villain.

Level of Familiarity:  While I know that I have heard this word used once or twice before, I was unsure of its exact definition.  I knew that calling someone a miscreant is an insult, but I was always under the impression that "miscreant" referred to someone who "makes mischief" or plays tricks.  I probably figured that because "miscreant" and "mischief" sort of sound the same.  However, I had no idea that it refers to a "depraved person" or "villain."  The actual definition of the word is much harsher than I initially thought.

Do I Want to Know This Word Well and Why?  I want to know this word well because I had only a basic understanding of it previously.  I want to know that I have learned the correct definition and usage of this word.  Also, the word is used so rarely, but it is such a powerful word, so I would like to know that I could use the word when the appropriate circumstances arise.

Do I Think Others Should Know This Word Well...If So, Who and Why?  I think others should know this word well, because it is such a better, more sophisticated way to insult someone than the words that most other people use.  It would be nice if others knew this word and used it when they are upset with someone else, instead of using other language that might result in more conflict and a less mature argument.
