Comments of chapter undefined of Harry Potter: A Certain Ancient Rune Professor of Hogwarts (TL)

I don't know where the term golden finger came up or why its appeared in several stories somewhat recently but its fricken weird. Everytime it makes me think of this silly gundam/mecha anime where his mechs finisher was the golden finger. Hope it's a short term fad cause it spoils the mood/flow everytime I see that eyesore term.
