English Other Slang Facetious linguistic contrivance?

I tentatively infer that it means "one who's thorough [a stickler, if you will] in their choice of words", further input on the notion purported, as I lack conviction here. Contexts: (And thanks in advance!)

1- Now that nirvana has become an English word, it should have its own English verb to convey the sense of "being unbound" as well. At present, we say that a person "reaches" nirvana or "enters" nirvana (...). But nirvana is most emphatically not a place. It's realized only when the mind stops defining itself in terms of place: of here, or there, or between the two. This may seem like a word-chopper's problem — what can a verb or two do to your practice? — but the idea of nirvana as a place has created severe misunderstandings in the past, and it could easily create misunderstandings now.

2- Is this the best voice for the story? Have you considered recasting it in the first person? I realise I’m stepping slightly beyond my remit as a word-chopper here, but it strikes me that this is already a deeply internalised point of view, so much so that the grammatical demands of third-person limited might be unnecessarily cramping your steez.
