When a baby boomer says some dumb shit and you can't even begin to explain why he's wrong because that would be deconstructing decades of misinformation and ignorance so you just brush it off and say okay.

A slang term used as a response to a statement made by a person from the baby boomer generation. I.e someone likely born between the years of 1945-1960.

The term is a logical fallacy called an ad hominem which addresses the characteristics of the person rather than their statement or position.

It is also used as a meme, and has started simp wars on twitter over the Bernie “ok boomer” girl.

One of the worst memes ever created.

When a baby boomer says or does something stupid and or does not make sense this is the correct response. Also very good to use when a boomer is being rude especially when they are judging people on things they do all the time.
*Non boomer 1 and non boomer 2 are walking in the mall and non boomer 1 almost knocks into a boomer*
Boomer: LOOK BOTH WAYS!!!!
*Boomer walks away really fast*
* Non boomer 1 and non boomer 2 turn to each other *
Non boomer 1: That woman walked away so fast I didn’t even get a chance to say “Ok boomer” !
Non boomer 2: I know right!

A reply given by zoomers and young millennials to anyone on the internet once they realize that they are a generational minority and will have to wait their turn until they become relevant enough to change American culture. A normal reply to this would be 'Ok loser,' or L.

Saying “ok boomer” is a lazy attempt at invalidating the opinions of those who you don’t agree with, without using any actual arguments. It was originally used specifically against boomers, but now it’s used against pretty much anyone even if the person is ironically younger than the person who typed “ok boomer”.

I don’t think paying CO2 taxes will save the planet. I don’t see how giving the government even more money is a solution.
