OK boomer

"OK boomer" or "okay boomer" is a catchphrase and internet meme used to dismiss or mock attitudes typically associated with baby boomers – people born in the two decades following World War II. The phrase first drew widespread attention due to a November 2019 TikTok video in response to an older man, though the phrase had been coined years before that. The phrase has developed into a retort for resistance to technological change, climate change denial, marginalization of members of minority groups, or opposition to younger generations' values more generally. Critics of the term perceive it as ageist, though that view has been publicly ridiculed. It has been noted as a marker of intergenerational conflict.
