WTF defined

I've noticed the acronym WTF appearing a lot in blogs and magazines lately. These letters stand for "what the f**k?" which is a slang way of asking "what in the world is this person (or group, etc.) thinking? Why are they doing this?" Sometimes people also use this expression to mean that they don't care about the outcome or result of something, and in this usage, the meaning is closer to "why not? What is there to lose?" For Wikipedia's take on this, and some potentially interesting links, click here.
