That's the phrase an Asian youngster uses whenever he wats to joke around. Nobody likes him because he doesn't know how to respect himself. He just thinks that people are hating on him. He has the I-know-everything-you-can't-tell-me-anything attitude. That's a clear sign of insecurity and ignorance.
I hate to admit that I was like that once. That's why I had to learn the hard way. I'm still learning.
The free world has countless youth with the I-know-it-all attitude. I want to be there to change that attitude because I've been there.
