perverse

What does "perverse" mean?
"Perverse" describes someone or something that deliberately behaves in a way that is unreasonable, unacceptable, or contrary to what is expected or desired. The mental image is of someone walking directly against a crowd or insisting on doing the exact opposite of a helpful suggestion, often with a sense of stubbornness or spite. In usage, it carries a negative, judgmental tone. It is often used to describe a person’s attitude (a "perverse sense of humor") or a situation that seems ironically or obstinately wrong (a "perverse outcome"). It is most common in formal writing or sophisticated conversation to describe behavior that defies logic.
