A word for someone who "does justice" to their (nick)name
I'm looking for an expression (preferably a single word) that denotes someone whose name or title fits them ironically too well. Names and nicknames are usually figurative, but I'm looking for idioms that I can use to make some word play in situations where they could be taken literally.
A few examples of what I want:
John the Headhunter took the meaning of person who does justice to their name too far. Literal murder is not part of his job description.
Mary "Smoking Hot" Smith, ironically doing justice to her name, did not manage to leave the building in time and was swallowed by the flames.
Joe "Please Don't Call Me Joe 'Joe Miller' Miller" Miller, as expected of a someone with that nickname, quit the interview after feeling improperly addressed.
This is actually a real person.
Solution 1:
"Aptly monikered" / "Aptly monickered"
From Collins:
moniker or monicker (ˈmɒnɪkə )
noun
slanga person's name or nickname
Your examples could scan as follows:
The aptly monickered John the Headhunter...
The aptly monickered Mary "Smoking Hot" Smith...
etc.
Solution 2:
I think the phrase you're searching for in these examples is "living up to their nickname":
John the Headhunter took the meaning of living up to his nickname too far. Literal murder is not part of his job description.
That does sound a bit off in that example. It's better to just say "lived up to":
John the Headhunter lived up to his nickname by committing murder on the job.
Mary "Smoking Hot" Smith lived up to her nickname by being swallowed up by the flames after not managing to leave the building on time.
Joe "Please Don't Call Me Joe 'Joe Miller' Miller" Miller, as expected, lived up to his nickname after being improperly addressed in an interview.
