It means OLD... It's a generation that's called the " Baby Boomers" but in slang if you say boomer it means old. So basically if you call someone/something a boomer then you are calling them old or calling the thing old.

An act in which a person grabs the sides of a metal folding chair tightly, pulling the ass as close to the seat as possible, and then farts as forcefully as possible.
The boomer reverberates loudly in all directions and resonates through the chair.

Boomer is anyone who's older than you and is either complaining about younger generation, saying he hates his wife, or just believes in outdated beliefs about any subject. It can also be someone who doesn't know modern slang very well, or uses it in a "non-cool" way (not in a way that zoomer would use it)
