Why do people seem to think that the ideas of being "crazy" or "unpredictable" are things to be proud of?

I’ve noticed that a lot of people seem to post a lot of memes on Facebook suggesting that they are crazy, or unpredictable, or weird, as if those traits are something super awesome and cool. It happens here on Fluther too.

What I think of when I hear the word crazy, is unstable or mentally ill.

When I hear the word unpredictable, I think of someone that I can’t depend on, or can’t trust.

What I think of when I hear that someone says they are weird, is that that person is someone who is purposely trying to cause a reaction, or to get attention.

I’d rather hear that people are intelligent, or compassionate, or creative, and then see examples.
