A much better way of saying things like WTF (What the WTF?), BTW (By the BTW), TMI (Too much TMI), or FYI (For Your FYI). Used when someone wants to make an emphatic point, or sound like a moron.
Kate was like, "I don't think we should see one another anymore," so I was like, "What the WTF? By the BTW, For your FYI, I've been seeing someone else, but I guess that's probably Too much TMI."
