Boomericum

Corpus boomericum
/ˈkɔ pəs bu ˈmɛrɪkəm/
*noun*
also shortened: Boomericum
informal, humorous, critical

The inherited body of outdated social assumptions, moral reflexes, taboos, warnings, and “common sense” rules from an older cultural era, especially when applied uncritically to a modern context where the original conditions no longer hold.

It refers to the archive of old-world logic that once made sense, or appeared to make sense, within its historical context, but has become misaligned with present-day social, technological, scientific, or cultural reality.

In academic or critical use, it also describes the inherited scaffold of outdated assumptions, concepts, models, or research traditions that keeps shaping new thinking after its original evidential, cultural, or methodological basis has weakened. It critiques epistemic fossilisation: treating old frameworks as permanent foundations rather than historically contingent structures to be revised, composted, or rebuilt.

It does not simply mean “boomer opinion” or “something old people think.” It refers to the deeper inherited archive from which such opinions may be drawn.

Concise definition:
The corpus boomericum is the inherited archive of outdated assumptions people draw from when applying old-world logic to a changed modern reality.
“You pulled that from the boomericum, lad.”
“That argument comes straight out of the corpus boomericum.”
“You should cite the Corpus boomericum in your sources.”
“This paper treats the Corpus boomericum as evidence.”
“Careful, you’re consulting the boomericum again.”

Boomericum

Boomericum
/ˈbu ˈmɛrɪkəm/
noun
short for Corpus boomericum
informal, humorous, critical

The fake source-library behind a boomerism: the inherited archive of outdated social assumptions, moral reflexes, warnings, taboos, and “common sense” rules that people draw from when applying old-world logic to a changed modern reality.

A boomerism is the surface cliché, such as “just walk in and ask for the manager” or “stop buying coffee and you can afford a house.” The Boomericum is the obsolete cultural archive being conjured as authority behind it.

It does not simply mean “boomer opinion” or “something old people think.” It refers to assumptions that may once have made sense, or appeared to make sense, but have become misaligned with present-day social, technological, economic, scientific, or cultural conditions.

In academic or critical use, Corpus boomericum can also describe old concepts, models, or research traditions that keep shaping new thinking after their original basis has weakened. It critiques epistemic fossilisation: treating old frameworks as sacred foundations instead of historical scaffolds to be revised, composted, or rebuilt.

Example:
Don’t post your projects online. Someone will steal your ideas.”
“Mate, you pulled that straight from the Boomericum.”
“Bro said you can buy a house if you stop ordering takeaway. That man is quoting directly from the Boomericum.”
“She said all drugs are the same because ‘drugs are drugs’. That’s not pharmacology, that’s the Boomericum speaking.”
“That paper treats 1960s assumptions like sacred law. Please cite the Corpus Boomericum in your sources.”
“Every time someone says ‘just work hard and the system will reward you’, the Boomericum gains another footnote.”

Boomerism 

Noun. A banal thought terminating cliche used by boomers and boomer sympathizers to convey the failed "conventional wisdom" of their generation. These cliche sayings are typical political or economic in nature and are refutable by hard real-world evidence.

The burden of evidence required to refute a "boomerism" is often substantial, requiring reference to the CPI (Consumer Price Index), Wage Index, or other economic data available on FRED (Federal Reserve Economic Data).

Millennials and Zoomers are too busy working their jobs as senior economic analysts, program directors, or serving coffee to pay off students loans, to refute boomerisms.

None the less, entitled boomers feel obliged to be provided with hours of high valued consulting work, at no cost, to disprove them. Millennials and Zoomers have adopted a strategy of responding to boomerism with the much less costly "Ok Boomer".
Boomer: "Well hello there youngster, what are you doing?"

40 y/o balding senior management wage slave: "Doing my taxes. It looks like I might be able to pay off my student loans and mortgage by the time I'm 83."

Boomer: "I see you are eating avocado toast there! You know, if you ate less avocado toast, and lived in a shoe, you could be free of debt by now!"

Waitress: "Now that's a boomerism, if I ever heard one."

40 y/o balding senior management wage slave: "Ok, boomer."

Boomer: "STOP! Ok Boomer is the new N-word!"

Boomerism 

An ideology which promotes the discrediting of ideas from any person or entity that disagrees with one's preconceived beliefs, regardless of their source's credibility. It is a common ideology among the "Baby Boomer" generation, born between 1946 and 1964, hence the title "Boomerism".
So many young people's ideas are shot down today without a second thought despite the fact that it will ultimately be their job to fix the issues created by the same group that is largely still in power; what a blatant display of Boomerism!

Argumentum ad Boomerum 

A very common modern informal fallacy. Most often it's an argumentation of the older generation (but also used by other generations) against anything remotely modern: pop culture, social media, technology and/or internet. This type of argumentation comes from Baby Boomer Generation, hence the name.
Bro 1: Wtf is this Tik Tok shit, those kids are doing stupid shit thats cringy AF.
Bro 2: Bruh, you just Argumentum ad Boomerum them.
Bro 1: Oh shit you're right, fuck.
