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.

Boomer: Kids nowadays are so allergic back in my day we just ate bees and wiped our asses with poison ivy.
Non-boomer: Ok boomer

Generic reply to baby boomer style thinking.

The equivalent of "Wow, you're so horribly wrong, but I don't have the time or energy to repeatedly explain something to you that you're not going to listen to anyway."

Millennials tried for so long to explain using facts and evidence that they don't actually have it that easy and they aren't just lazy, but it became very clear that boomers don't care about facts, evidence, or reality for that matter. So this is what has resulted.

"If you just stopped eating avocado toast you'd be able to afford housing and healthcare in no time."

"Ok boomer."
