Keshikaran (けしからん - Disgraceful)

We say keshikaran (けしからん) when expressing that something is contrary to reason or disgraceful.

Keshi (けし) means that something is abnormal, and karan (からん) came from karazu (からず), which is a negative word.

Therefore, keshikaran means that something is not just abnormal, it is extremely abnormal.

This term tends to be used by senior men.

However, these days on the Internet, people (especially young people) sometimes use keshikaran for sexually women or cute gestures of animals as the meaning of "it's too sexy/cute."
