Skitt's Law is an internet proverb derived from the Usenet era, specifically attributed to a user named Skitt in the late 1990s. The law states that any post correcting someone else's spelling or grammar will inevitably contain an error of its own. It is a specific variation of Muphry’s Law and is frequently invoked in comment sections and social media threads to mock people who attempt to be pedantic but fail. The meme typically features screenshots of ironic mistakes or text-based jokes highlighting the recursive nature of internet arguments, where the act of being a 'grammar nazi' leads to immediate comedic justice.
