The Walmart meme ecosystem primarily revolves around the 'People of Walmart' phenomenon, which gained massive traction in the late 2000s via photo-sharing websites documenting the eccentricities of shoppers. Over time, it evolved into a broader category representing the chaotic, 'anything goes' atmosphere of big-box retail. These memes are often used to illustrate social awkwardness, extreme budgeting, or the surreal experiences one encounters while shopping during unconventional hours. It serves as a relatable cultural touchstone for the unpredictable and often humorous nature of suburban American consumer life.
