Yo yo Yow Chen?????

Freaks,
If you ever see a person that looks or is the following: Chinese, Japanese, Asian, or anything else that follows those categories, never say yo. Not to them, but to anyone around them and here is why:
U: Yo! Sup?
Chinese person: I do good.
U: Huh?
Chinese person: You say name. You say Yow. I Yow Chen.
U: Oh, um I wasn't talking to you...
Chinese person: WHAT? That just offensive. That slang. That bad.
U: Uh, it just means hi.
Chinese person: Then why you no say hi? You say yo? Offensive.
U: K, hello.


And that is why!
