Being technically right in a way that makes everyone else wrong on purpose.

means An excessive, finicky insistence on rules, details, or technical correctness, especially when it's beside the point.

from Traces back to the French pédant and Italian pedante, words for a schoolmaster or tutor — someone paid to drill grammar and rules into children. The sense curdled over time: from 'teacher' to 'person who treats every tiny rule like it matters more than the lesson.' The deeper root is murky, possibly tangled up with the Greek paideuein, 'to educate' — so pedantry has been quietly mocking teachers for centuries.
