whacko
Someone mentally unhinged
Whacko is an informal term for someone considered crazy, eccentric, or irrational: Some whacko called the office threatening lawsuits.
As an adjective, it describes bizarre or mentally unstable behavior: whacko conspiracy theories.
The word is dismissive rather than clinical—used to write someone off as not worth taking seriously.
Also spelled wacko.
