A response when you don’t have the time or energy to correct or explain something to someone older. Often times older people are more entrenched in their views and experiences that explaining something falls on deaf ears (no pun intended). Hence a lot of
conversation about things like the environment, (work place etiquette, gender equality,
intermittent fasting, what’s considered hate speech and what’s
socially acceptable, the hiring process, etc) leads nowhere. So save yourself the headache and yelling by saying “ok, boomer” and leave. It’s important to note that as Gen X ages (generation after boomers), it can apply to them as well. It’s basically what you say when explaining/debating a topic isn’t worth the effort anymore.
Boomer giving advice: "Just call/go in and ask if they're hiring!"
Someone looking for a real job: “you can’t, you have to submit your resumé online first or they’ll turn you away at the door”
Boomer giving advice: “We used to just walk in and ask to see the hiring manager, go try that!”
Someone looking for a real job: “...ok, boomer”
Or
Clueless boomer: “I don’t see why Jews are so pissed off about a few cartoons poking fun at them or that parade in Aalst (Belgium) where people wear some silly costumes?”
Respectful citizen: “Because it’s completely
anti-Semitic, and it’s likening them to ants! Literally! And do you not remember how the holocaust started? It’s
the little things!”
Clueless boomer: “ya but it’s a once a year festival that’s hundreds of years old that pokes fun at everyone. It’s all in good spirit”
Respectful citizen: “...ok boomer,
I have to go. Covid-19 is coming and I need more toilet paper, don’t have time to debate this.”
