A fun janitor is any person who takes a fun situation, and dulls it down. Either by forcing people to focus on a different, less-fun task, or by ruining their good time altogether.

Being a fun janitor is not a good thing, and it implies that you're "cleaning up the fun" or "sweeping all the joy in life under the rug".

Don't be a fun janitor.
