re: “Congratulations. You made up a new tag.”
To the astute; note, the “/s” (implying the foregoing was sarcasm) is not a formally defined tag either, yet, it is widely used WHEN one suspects the target audience MAY not get subtle, sarcastic, humor.
This use of a new ‘tag’ is in the category of ‘literary license’. Furthermore, it gets entered into the long-lasting ‘official’ record that one *intended* the foregoing, branding it as intended, unlike one Adam Schiff who claims AFTERWARD a particular ‘work’ was fanciful footwork in the vein of artistic or literary license.
It has been in use on FR as long as I've been here (since 2004).
