A guilty pleasure is something we do that we enjoy, but feel guilty about. Primarily, the guilt is because we don't want anyone else to know about said pleasure. For example, if you're a health food nut, eating junk food late at night might be a guilty pleasure.
Well, I have my own guilty pleasures that I'm gonna out myself on now.
Why? Because I lost a bet to Chaz and I have to honor said bet.
