The 'Clap Those Alien Cheeks' meme gained massive notoriety in 2019 as a primary slogan for the satirical Facebook event 'Storm Area 51, They Can't Stop All of Us.' What started as a joke about raiding the top-secret military facility evolved into a viral phenomenon, blending internet horniness with sci-fi absurdity. The phrase implies a humorous, overly confident motivation for breaching the base: to engage in intimate acts with extraterrestrials. Today, it is used to represent reckless enthusiasm for a dubious goal or as a nostalgic callback to the peak of Area 51 meme culture.
