The 2013 April Fools' Day meme commemorates one of Reddit's most ambitious social experiments: the Great Reddit Civil War. On April 1, 2013, the platform divided its entire user base into two competing factions—Team Orangered and Team Periwinkle—based on the iconic colors of the upvote and downvote arrows. Users were granted chaotic inventory items, power-ups, and hats to decorate or disrupt comments, leading to a site-wide frenzy of competitive posting and community tribalism. Today, the meme serves as a nostalgic badge of honor for long-time Redditors and is frequently used to represent arbitrary yet passionate internet conflicts or team-based rivalries.
