The trend represented a rejection of the expectation to produce elaborate home-cooked meals and celebrated the simplicity of just eating what's convenient. The term hit home particularly with younger people and those rejecting traditional gender roles around cooking. The trend also connected to broader conversations about food culture, meal prep culture, and the pressure to present perfect meals on social media.
