An old person who doesn’t understand this century

A derogatory term delivered to terminate debate with persons having a mindset containing all of the worst aspects of the Baby Boomer aesthetic, including:

- the rejection of science in favor of personal opinion
- clinging to a cherry picked examples of 'traditional values', and the 'good old days'

- blaming racial groups, immigrants, or anyone without economic power for the economy

- referring to another person as a 'snowflake' while getting extremely irate about some mundane irrelevant detail like where Trans people pee.

The term is delivered to declare that the person being labelled has lost all credibility and that conversation is now closed. While boomers are often members of the Baby Boomer generation, the term 'boomer' may be equally applied to any person who rejects data on the basis of personal prejudice.

Onyekachi Igwe is the prime definition of a boomer, he is old and annoying!

Someone born during the "baby boom" following WWII. Boomers were coddled by their parents and led to believe that they could achieve anything they dreamed of and that they were perfect just as they are. They deeply resent the society they created based on this terrible advice, and the progeny they misguidedly trained to perpetuate it. As a result, reality bites boomers in ways more acutely painful than subsequent generations can possibly understand.
