"I Am Rectangular" is a viral meme based on a song by Canadian entrepreneur and musician Sean Stephens. The track features the catchy yet surreal lyrics "I am rectangular, I feel it in my bones," which quickly captured the internet's attention on platforms like TikTok and Instagram. Originally intended as an anthem for being an "outlier" or not fitting into a "circular world," the song's literal imagery and Stephens' earnest performance turned it into a massive hit for ironic humor and creative remixes. Users often pair the song with images of boxy objects or use the lyrics to celebrate their own unique, non-conformist identities in a humorous way.
