Sophie Vershbow has seen her share of "OK, boomer" memes in recent weeks. The phrase that's suddenly everywhere is meant to convey a fundamental disconnect between younger generations and baby boomers who cling to outdated, off-base ideas. To Vershbow, a 30-year-old social media manager, the sentiment behind the memes is this: "I think it's a dismissive, 'OK, whatever you say.' " Case in point: 25-year-old New Zealand lawmaker Chloe Swarbrick recently hurled the "OK, boomer" phrase at older colleagues heckling her during her speech in support of a climate change bill.
