Weird Twitter refers to a loose collective of users who pioneered a surreal, absurdist, and anti-humor style of microblogging beginning in the late 2000s. Characterized by intentional typos, non-sequiturs, and bizarre scenarios, the movement was led by iconic accounts like @dril and @horse_ebooks. Unlike traditional jokes, Weird Twitter focuses on the breakdown of language and social norms, often satirizing the platform's self-seriousness. Today, it remains a cornerstone of internet subculture, influencing modern irony and the aesthetics of 'shitposting' across all social media platforms.
