The 'Zucc' meme refers to the various internet jokes surrounding Meta CEO Mark Zuckerberg’s supposedly robotic or non-human behavior. The term gained significant traction during his 2018 testimony before the United States Congress, where his stiff posture and mechanical water-sipping became instant viral sensations. Users often joke that Zuckerberg is either an advanced AI or a reptilian humanoid attempting to blend into human society. Common tropes within the meme include his obsession with 'Sweet Baby Ray's' barbecue sauce, his intense facial expressions, and his metaverse avatars, all used to satirize the social media mogul's perceived disconnect from everyday human emotion.
