Definition: Uncouth; (Pronounced: uhn-kooth) Old English; adjective
1. Lacking good manners, refinement or grace.
Why I love this word:
I first learned this word through John Green a few months ago in one of his Mental Floss videos. Then it reappeared today on a show I was watching on Netflix. The scene was this pretentious and incredibly rich family hosting a soiree. Over the dinner table a young lady said something that wasn't very ladylike and apologized by saying "how uncouth of me." The definition of the word explains it well; if someone is being uncouth, they aren't considering the world and the people around them and is resulting in being known for having poor manners, and that isn't very Gracious behavior.
