Wheaton's Law is a legendary internet axiom coined by actor Wil Wheaton during a 2007 keynote at the Penny Arcade Expo (PAX). The law is elegantly simple: 'Don't be a dick.' While originally aimed at online gamers to encourage sportsmanship and discourage griefing, it quickly evolved into a universal rule for all digital and social interactions. In meme culture, the phrase is often paired with a photo of Wheaton himself or used as a reaction to toxic behavior. It serves as a concise, powerful reminder that decency is the bedrock of any functioning community, becoming one of the most cited guidelines in the history of internet culture.
