Boomer

Boomer (noun / slang)

Definition: Strictly speaking, someone born in the post-war baby boom (1946–1964). In everyday chat? Anyone who pecks at an iPad screen with one index finger, whinges on local Facebook groups, or thinks you can easily buy a house if you just stop buying meal deals.

Pronunciation: /ˈbuː.mə/ (boo-muh)

Where It Comes From: Started as dull census jargon after the Second World War when birth rates spiked across Britain and the West. It stayed buried in sociology textbooks until the late 2010s, when younger folk got sick of being lectured about hard graft and house prices by people who bought four-bed semis for twenty grand in the eighties. The phrase “OK Boomer” took off online, turning a demographic tag into a weaponised eye-roll.

How People Actually Use It: Nobody checks your birth certificate first. It’s a state of mind.

You’ll get called one if you struggle with contactless payments, complain about background music in a pub, or print out boarding passes on paper just in case. It’s tossed around family group chats, dropped when an older relative gives useless job-hunting advice (“just walk in and ask for the manager”), or used playfully on a twenty-something mate who acts like an old pensioner.

Examples in the Wild:

• “My dad still signs off his WhatsApp messages with ‘Regards, Dad’ like an absolute boomer.”

  Translation: “He texts like he’s sending a formal letter in the post.”

• “Told me I’d have a deposit saved if I quit buying coffees—proper boomer logic.”

  Translation: “Gave me completely out-of-touch financial advice.”

• “Why are you holding your torch like that to read the menu? Proper boomer vibes.”

  Translation: “You look hilarious struggling to see in a dimly lit restaurant.”
