A question for the folks

[ericcoleman]

What is your favorite text/internet abbreviation (or abbreviations)?

What is your least favorite?

And I'm not asking for your opinion on such things in general ... I'm looking for specific text-speech and what they mean

I like emoticons to clarify what my attitude was. Sometimes I am not smart enough to make the words do that. They should not be used excessively or to soften mean words.
I hate ROFL.
I like WTF? But not as just any abbreviation. I like it as graffiti or in the body of an email. As a stand alone comment it is pretty lame.
