TanaCon refers to the disastrous 2018 fan convention organized by YouTuber Tana Mongeau after a dispute with VidCon. Marketed as a more affordable and fan-friendly alternative, the event quickly devolved into chaos when thousands of attendees were left waiting in the sweltering heat outside a venue that was significantly over capacity. Often dubbed the 'Fyre Festival of the YouTube world,' the event became a goldmine for meme culture, particularly after Shane Dawson released a multi-part documentary series investigating the failure. Today, the TanaCon meme is used to represent catastrophic planning, over-hyped promises that lead to disappointment, or any situation where expectations clash brutally with a messy and unorganized reality.
