It's kind of like saying someone is "the man" in English.

Worth noting that "the man" may instead mean police/government/etc, usually with negative connotations. So context may make this less appropriate as a synonym than "righteous dude" as mentioned above.

That's "the Man". :)

Capitalization is very important here! Also, e.g. if you are helping your uncle Jack off a horse, etc.
