A put-down used to tell an ignorant or closed-minded person of the baby-boomer generation that you do not respect their opinion because it's built on misinformation or ignorance so great that it's unreasonable to try and undo it all in the current conversation. Typically, one who uses this phrase does so because they realise that the person they're talking to would not be willing or able to enter a reasonable discussion about their misinformed opinion.
Boomer: "You millennials are so lazy, you think you're entitled to an easy life. You don't know how the world really works. By the time I was your age I'd paid off my mortgage because I worked hard."
Millennial: "OK boomer"
