Dobe is the Japanese slang word for “idiot”. Chinese youngsters use it to refer to a ridiculous person who is a stranger, or a funny one who is a friend.
We can comprehend this composite word as a funny 2B. Simply put, it means someone is funny, a little silly and cute. With its widespread use, more and more people consider it a neutral word. If we use it to describe a stranger, we are more talking of a stupid stranger. If it alludes to a friend, then it is used to mock and make fun of the friend.
