wacko
Off-the-wall person
Wacko is informal for a crazy or eccentric person: Some wacko called the office three times today.
As an adjective, it describes irrational or bizarre behavior: a wacko conspiracy theory.
The word is dismissive rather than clinical—you might call someone wacko for beliefs you find absurd, not for genuine mental illness.
