The line comes from the 1994 comedy film Dumb and Dumber, starring Jim Carrey as Lloyd Christmas and Jeff Daniels as Harry Dunne, two well-meaning but dim friends on a cross-country road trip. The Big Gulps exchange became a favourite quotable moment because it sums up their simple, cheerful outlook in just a few seconds. As short soundboard clips and reaction audio spread online, creators began reusing it for videos about large drinks, road trips and over-the-top portions. It remains popular because the joke needs no context and instantly signals light-hearted, 1990s movie nostalgia.
