Facebook/Meta employees, if this still isn't your cue to resign, I don't know what is.
It is certainly popular enough in the Seattle area at places that are not Microsoft. There are enough ex-MSFT people floating around (really, a lot of them) that you hear it often.
For all the other comments, as an employee, would you really care?
It might sound dumb, but it’s also fun, self-deprecation humor if one worked there.
This is Meta's way of keeping you in to continue destroying lives.
Similar deal to most other corporate culture.
