The 'Day of the Pillow' is a dark humor trope originating from imageboards like 4chan, specifically within threads discussing the economic and cultural divide between Boomers and younger generations. The phrase refers to a fictional, hyperbolic event where the elderly are 'put to rest' with a pillow, symbolizing a forceful yet quiet end to their perceived dominance over social resources. Usually featuring Wojak characters or hospital-themed imagery, the meme is used satirically to vent frustrations about the housing market, inflation, and political stagnation. It represents the most extreme, absurdist version of the 'OK Boomer' sentiment, framing generational turnover as an inevitable, albeit grim, conclusion.
