The 'Which Disney Are You?' filter became a viral sensation on Instagram and TikTok in late 2019, sparking a trend of users recording their reactions to the random character selection. Created as an Augmented Reality (AR) effect, the filter cycles through icons of classic Disney figures above the user's head before stopping on a final result. The meme's popularity stems from the often-ironic results users receive, such as a self-proclaimed 'princess' being assigned a villain like Ursula or Jafar. It is widely used to showcase personality traits, humorous disappointments, and the unpredictable nature of social media filters.
