Usually your parents but someone who hates Millenials and say things like disgraceful. Heres a quick tip to limit boomer's lifespan -5 years . when they talk to you about how wronged they have been by their phone provider over 37 dollars turn on the tv and wait just a little bit too long to respond possibly with "I don't think so" and when they ask why say "ah just because" with no actual serious argument
"some boomer got pissed at me because I left the bathmat on the floor at it was too soggy. I just waited for yelling at me to bore them and I said fuck off."

A true gentleman. One of the last few of a dying breed. A humble motherfucker with a big-ass dick.
Hoe #1: Who is that sexy piece of ass?

Hoe #1: I would totally hum "The Farmer in the Dell" while going down on that man.

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.
Tom: "Holy crap! Did you hear that?"

Tom: "Naw, Vinnie just did a boomer!"
