The McDonald's Mulan Szechuan Sauce meme stems from a legendary 1998 promotion for Disney's 'Mulan' that lay dormant until the 2017 Season 3 premiere of 'Rick and Morty.' In the episode, Rick Sanchez reveals his life's mission is to taste the discontinued sauce once more, sparking a massive real-world demand that led McDonald's to briefly re-release the product. The meme characterizes desperate longing, niche obsessions, and the chaotic power of internet fandoms. It is commonly used to joke about things that are extremely difficult to find or to mock the lengths people go to for corporate nostalgia.
