Corrugated-sheet-generation

[Zipporah Schumaker]

Describes mostly older generations (boomers and older) who have difficulties adapting to modern society with its changing values, new technology and younger generations.
Origin:
Borrowed from German Wellblech-Generation (literally: [corrugated-sheet-generation])
While boomers still tend to name millennials generation Y (modest reference to themselves), millennials fought back, and renamed the older generations.
It refers to a [parable] about the difference between the generations: While we millennials and younger build real houses, they boomers and older still build theirs with [corrugated] sheets only.
