Januarian
A Januarian is one who is really gung-ho to do stuff and accomplish great stuff in January, and has lost all interest and motivation by February. We all know Januarians.
Examples of Use:
1. My gym is so full of Januarians that I have to wait 20 minutes to use a treadmill….in January.
2. I’m such a Januarian, that I took my New Year’s Resolutions, and burned them.
Now, if you can’t even make it through part of January, then it might be that you are not a Januarian, but that you are just plain old lazy! You be the judge.
