Kook

In simple language, the internet slang term “kook” refers to someone who is considered strange, weird, or eccentric. It is commonly used to describe people whose behavior, thoughts, or beliefs are way out of the ordinary.

Examples:

1. Sarah’s new roommate is such a kook. She spends hours talking to her plants and believes they can communicate with her.
2. Did you hear about that conspiracy theorist who thinks aliens control the government? He’s a total kook!
