Definition

A person born during the post-World War II baby boom, typically between 1946 and 1964; in modern slang, used dismissively to refer to anyone perceived as out-of-touch or resistant to change, regardless of actual age.

Example Usage

Her uncle dismissed the new technology as unnecessary—such a boomer take on progress.

Origin

Originally referred to the demographic surge of births following WWII; the slang usage became prominent on internet forums in the 2010s.

Fun Fact

The term has evolved so dramatically that it's now more about attitude than age, leading to ironic uses like 'okay boomer' becoming a meme in 2019.
