wtf

Oh, I could very easily be wrong. You know what happens when you play with coloring books too often. ;-)

That's interesting; I wonder where you would have picked it up? Surely before the internet the phrase was almost always spoken rather than written? I mean, wasn't informal conversation almost purely a verbal thing? Other than ofice memos, notes passed in class - but that can't compare to the volume we have now.

It's an Internet acronym? I was sure I'd picked it up much earlier than all that.

The only internet acronym I'm not embarrassed to use. WTF?
