The Autism Challenge refers to a series of social media trends, most notably on TikTok, where users reacted to specific audio clips or engaged in challenges meant to highlight neurodivergent experiences or behaviors. While some iterations of the challenge faced controversy for their portrayal of disability, many individuals within the community reclaimed the concept to share relatable content and foster self-advocacy. In meme culture, it is frequently used to signify a sudden realization of specific habits or to humorously acknowledge neurodivergent traits in a lighthearted, community-driven way, turning personal experiences into viral, shareable moments.
