I found this article while surfing Microsoft website about child safety when using the internet. This particular article is trying to educate parents with the slang involved in the internet.
words like l33t, h4x0r, j00,pr0n are explained in the articles as well as guidelines to understand such words when parents came accross them. This articles also may serve as a reference to people who wants to learn l33t5p33k.
