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.

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who's older than you and is either complaining about younger generation, saying he hates his wife, or just believes in outdated beliefs about any subject.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)

Boomers are people from older generations that don't give a fuck about what we do nowaday and make you repeat THEIR childhood or whatever. They also don't know our language very well for example, they have no idea of the concept of slang. Long story short: Adults and older people don't know what we do and don't understand what we normally do in our daily lives.

a "slur" against baby boomers.
People are against as it is "ageist" and they say it is the n-word of ageism.
