The Doritos and Mountain Dew meme represents the peak of mid-2010s 'MLG' (Major League Gaming) montage parody culture. Originally stemming from heavy corporate cross-promotion between the snack brands and franchises like Halo and Call of Duty, the pairing became a satirical symbol for the stereotypical 'hardcore gamer.' Internet users began using these products in overly edited videos filled with airhorns, hitmarkers, and lens flares to mock gaming tropes. Today, the combo remains an iconic shorthand for gaming nostalgia, representing the high-energy, snack-fueled grind of late-night multiplayer sessions.
