hy·poc·ri·sy (noun): a pretense of having a virtuous character, moral or religious beliefs or principles, etc., that one does not really possess.
Remember that whole thing with former President Bill Clinton and Monica Lewinsky? And how former speaker of the house Newt Gingrich was leading the charge against him? Well, it turns out Gingrich was having his own affair at the time.
Yup, he was committing adultery just like Clinton, and at the same time.
I hate that guy.
