The phrase kiedyś było is a common Polish expression of nostalgia, often used ironically online to mock complaints that everything was better before. Shortened and clipped as kurr no kiedys bylo, it spread on Polish soundboards, TikTok and short video edits as a reusable reaction sound. Users drop it under posts about inflation, ageing, gaming changes and remakes, where the joke is the exaggerated sigh of disappointment. Its popularity comes from how instantly Polish speakers recognise the sentiment, even without context from a specific show or creator.
