The Mayweather vs. Pacquiao meme stems from the long-awaited boxing match between Floyd Mayweather Jr. and Manny Pacquiao in 2015. While billed as the 'Fight of the Century,' the actual bout became a source of endless internet humor due to Mayweather's defensive strategy and frequent clinching. The most popular versions of the meme use photos of Mayweather hugging Pacquiao to represent someone avoiding their responsibilities or 'clinging' to a situation. It has since evolved into a versatile template for depicting any high-stakes rivalry where one side is perceived as being overly defensive or elusive.
