boomer (30-year-old)
What does boomer (30-year-old) mean?
Not an actual baby boomer. A specific meme caricature: the millennial who's barely 30 but already behaves like he's pulling up the ladder — same five franchises, same beer, same opinions, ages himself in dog years. The label later broadened to any millennial accused of being prematurely cringe or out of touch with Gen Z.
"Posting a 'doggo' meme in 2026 is straight 30-year-old boomer behaviour."
Origin
'30-Year-Old Boomer' wojak meme, popularised on 4chan and Reddit around 2018. Premise: a balding, slightly paunchy millennial who drinks Monster Energy, watches Marvel and thinks he's still young.
