As the mother of a 15-year-old boy, I've heard "OK Boomer!" way more times than probably necessary. I have to admit, the first time I heard it, I reacted negatively and loudly announced "I'm not a Boomer!" (I'm close. But technically, no, I'm not a boomer.) This reaction of course delighted my son and now it is his mantra every time he talks about something I don't understand or every time I talk about something he doesn't understand.
