A term used to describe someone of an older generation (Baby Boomer). Often used as an insult to describe someone who is behind the times, lacks understanding of new terms, and lacks the ability to use technology.
“You heard of that boomer streamer?”
“Who? zAceX12? The one that streams on Twitch at twitch.tv/zAceX12?”
“Yeah, that guy is a boomer”

Get the Boomermug. An Australian boy who loves hugs and cares a lot about his fans. Usually is seen with blonde hair but dabbles in dying it dark. The person may also have seagull like arms and dimples. If you see this person roaming the streets, yell "boomer!" and go give them a hug :)
Person A: Hey, did you see that guy with abnormally long arms?
STAY: Oh yeah, don't worry. That's just boomer Chan going to buy some milk.

Get the Boomermug. Short for "Baby Boomer"...
A "Baby Boomer" is an adult human within the age range of 60 to 80 years old, "Baby boomers" are the generation which preceded "Gen X"...
"Boomer" is most commonly used by members of the "Millennial" generation, usually to INCORRECTLY refer to their parents whom they are rude to, disrespectful of, & do not appreciate for no legitimate reason at all...
Whether used incorrectly to refer to their parents, or correctly to refer to their grandparents, the term "Boomer", when used by a "millennial", is almost always followed by unethical, immoral derogatory slurs intended to express intolerance & disrespect for them....
THAT is the PROPER, ACCURATE "Urban" definition of the term "Boomer"...
(& No, I am NOT a "Boomer", I am just NOT a spoiled, self entitled, punk, ingrate is all.)

(common incorrect usage example) "I HATE my "Boomer" parents & their "8o's Rock" & their doing everything they could have to make my childhood a utopia I never appreciated because I deserved so much more."
(Rare correct usage example) "I know nothing at all about "Boomers" because my grandparents are old & inferior to me so I don't care about them, but I do somehow blame them for how much my life sucks."
