My kids went through a phase like that when Sinead O'Connor was popular. They seemed to think it was exceptionally cool to write "B4" instead of "before." They grew up, and now they think it's obnoxious.
I also thing all the Internet-speak acronyms are quite obnoxious, unless they are used very sparingly and only when their use is humorous. Otherwise, I think ROTFLMAO is about as tedious as a human being can get.
I see there's a thread name that begins with the prefix FR:. I wonder what the heck THAT means.....
