1. A communist dictator, especially of the "I'm gonna kill you ALL!" type.
2. Anyone with communist leanings.
3. Anyone with a hotness factor close to that of Stalin, who as we all know was the HOTTEST COMMUNATOR EVAR!!!1!1!
4. As a verb, to threaten someone with a particularly violent death.
So, I'm thinking of becoming a violent communist dictator when I grow up.
-Oh, you mean a communator?
Don't make me go communator on you!
