The 'Who Are You People' meme originates from the Season 2 episode of SpongeBob SquarePants titled 'Prehibernation Week,' which first aired in 2001. In the scene, Patrick Star is rudely awakened from his sleep under his rock by a large crowd of people searching for SpongeBob, leading him to scream the iconic line in a state of startled confusion. The meme gained significant traction on platforms like Reddit, Tumblr, and Twitter as a way to express social anxiety, being an outsider in a group chat, or general bewilderment at a trending topic. Its versatility lies in its ability to perfectly capture the feeling of being suddenly confronted by a community or situation you simply do not recognize or understand.
