The 'Grammar Nazi' meme refers to an internet persona who is obsessively pedantic about correct spelling, grammar, and punctuation. Emerging in the early days of internet forums and newsgroups, the term was popularized as a way to describe users who prioritize linguistic precision over the actual content of a discussion. The imagery often features the 'Grammar Nazi' logo—a red banner with a white circle and a blue letter 'G'—or characters depicting strict authority. It is used to mock those who derive satisfaction from correcting others' minor linguistic slips, highlighting the tension between casual internet slang and formal writing standards.
