The Great Myth of Advertising
If you want to annoy someone in their late 30s, joke that all they care about are avocado toast points or beard grooming or running off to Coachella when a project needs to be finished. Because they are millennials.You can also stereotype Baby Boomers or Generation X(1) and get a rise out of them.

Advertisers created these sweeping generalizations based on demographics.
