Nutcase

A nutcase is an informal and often derogatory term for a person who is considered eccentric, strange, or even mentally unstable. The term implies behavior that is perceived as irrational, peculiar, or disruptive. It can be used to describe someone whose actions or beliefs are significantly outside the norm, ranging from harmless quirks to more serious mental health concerns. The intensity of the term can vary depending on context and intent; it may be used lightheartedly or as a more malicious insult. Use with caution, as it can be offensive.
