The Mark Zuckerberg meme phenomenon stems from several viral moments involving the Meta CEO’s seemingly unnatural public behavior. Key highlights include his 2018 congressional testimony where his stiff posture led to 'Zuck is a robot' theories, and a 2020 photo of him surfing with an excessive amount of white sunscreen on his face. Other popular variations include his obsession with Sweet Baby Ray's BBQ sauce and his often-criticized Metaverse avatars. These memes generally poke fun at his perceived lack of human relatability, turning the tech mogul into a versatile symbol for awkwardness or corporate detachment.
