"OK boomer" or "okay boomer" is a catchphrase and internet meme that has been used by Millennials and Gen Z 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. Considered by some to be ageist, 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. The phrase has also been used commercially to sell merchandise and has been the subject of multiple trademark applications. From Wikipedia
