I "live under a rock" because I don't get your reference? Judgmental much? Not everyone is like you. Get over yourself. :)
Yes you live under a rock that's what the expression is for. The people who are clueless or oblivious to a very common or widely known things. Try to keep up.
Allso getting mad at us for living under a rock is you problem and only works against you.
You could of typed into Google what I was talking about and instantly found and saved us all of your ignorance but the need to make a scene is something you crave more than truth.
