The Pepsi Dog meme, often overlapping with the 'Bepis' internet slang culture, features a dog looking particularly satisfied, surreal, or hyper-focused alongside a bottle or logo of the famous soda brand. Originating from the wave of ironic 'Cursed Images' and surrealist humor on platforms like Tumblr and Reddit in the late 2010s, it taps into the weirdly specific niche of brand-fixated animals. The meme is primarily used to convey a state of intense refreshment, chaotic energy, or mock-corporate loyalty. Its popularity persists due to the inherently funny juxtaposition of a domestic pet and an aggressive marketing aesthetic, making it a staple for social media users who enjoy nonsensical and high-energy humor.
