This is not a duplicate of Please improve the description of the Organizer badge, as that asks to make it more clear that it doesn't apply to one's own questions; my request is totally different.
Ever since the former retag privilege (which allowed 500+ rep users to make tag edits without needing to have them approved as suggested edits) was removed, the word "retag" is pretty much not used in the software
...except in the short description of the Organizer badge, which is "First retag". This is not at all clear, because the word "retag" is only mentioned once in the help center, on a totally unrelated page, and the word is only defined in an unrelated question. This has caused users to get confused.
Can we change the short description of the badge to "First tag edit"?
Per Shog's answer here and evidence from recently awarded badges, animuson's comment below that the badge is only awarded for tag-only edits is incorrect; the badge is awarded for tag edits that also modify the title or body.
