Thats right. You read the title correctly, Microsoft now has "A parent's primer to computer slang" on microsoft.com. Their reasoning? "While it's important to respect your children's privacy, understanding what your teenager's online slang means and how to decipher it is important as you help guide their online experience. While it has many nicknames, information-age slang is commonly referred to as leetspeek, or leet for short. Leet (a vernacular form of "elite") is a specific type of computer slang where a user replaces regular letters with other keyboard characters to form words phonetically'creating the digital equivalent of pig Latin with a twist of hieroglyphics."
A few excerpts for your reading pleasure:
"pwn": A typo-deliberate version of own, a slang term that means to dominate. This could also be spelled "0\/\/n3d" or "pwn3d," among other variations. Online video game bullies or "griefers" often use this term.
"ph": often replaces "f," as in "phear" for "fear" (as in "ph34r my l33t skillz") and vice versa, such as spelling "phonetic" as "f0|\|371(."
