I once told a coworker doing dumb shit to “Take a minute, go outside and count your chromosomes.”

I also told another one “You are wasting my time AND the time of the tree that makes your oxygen”

I never used the words idiot or retard, but I meant every word. Because if being bitched out for unsafe behavior hurts your feelings, you’re really going to hate being thrown offsite and having to beg HR to keep your job. Because those are my choices, bitch you out or write you up.

I don’t see a point of constantly shifting the words.

There is no point, that is just what humans do with language. It is never static. Always evolving.

Every generation crates new slang to differentiate themselves from their parents. Give it enough time and Latin turns into French, Spanish, Portuguese, Italian and Romanian because each local population changed Latin in different directions.

It is even happening to English. There are now several sub-languages of English according to linguists.

UK English.

US English

Aus English

Singapore English

International English

To name just a few.
