The 'Sasa Lele' meme is a classic example of the 'Don't Dead Open Inside' trope, where text layout leads to a hilarious misreading. It originated from a photo of a store's glass door where the word 'SALE' was stacked vertically on two separate panels. While intended to be read top-to-bottom as 'SALE SALE', most viewers naturally read it left-to-right, resulting in the nonsensical phrase 'SASA LELE'. The image went viral across platforms like Reddit and Tumblr as a celebration of poor graphic design. It is commonly used to mock confusing layouts or to represent a state of total linguistic confusion, often paired with reaction images of people looking puzzled.
