4chan greentexts are a unique storytelling format that originated on the anonymous imageboard 4chan, characterized by the use of the greater-than symbol (>) to turn text green. Typically beginning with 'be me' to establish a persona, these posts evolved from simple technical workarounds into a distinct cultural phenomenon for sharing anecdotal, humorous, or bizarre life experiences. The format's minimalist style and 'anonymous' vibe allowed it to transcend the board, becoming a staple of internet humor on platforms like Reddit and Twitter, where users continue to use the greentext syntax to frame comedic narratives and legendary 'tales of' specific characters or events.
