This is probably a dumb question but I occasionally see the term "Cad" in TRP. At first I thought it was just people mispelling Chad, but I've seen it in yesterday's Rational Male post and there's an endorsed contributor called something like theultimateCad which makes me think this is not a typo. So is Cad the same as Chad or is this a different term that I am not familiar with. Is Cad a variation on the concept of Chad?
