I've been struggling for a while now to figure out why Philip Rivers is such a jackass. Why did he heckle Jay Cutler? Why did he scream at Chargers fans? Why did he scream at the Colts' bench? And why did he get into a shouting match with a Colts fan? There must be something that's got this guy wound extra tight.

Yes, my friends, there is. And this video proves it. Philip Rivers is a huge fan of.....chastity.

Sure he may have 3 kids with his high school sweetheart and #4 on the way, but something tells me Rivers is, uh, kind of frustrated he missed his chance to pull a Romo. Either that or he's going chaste in between those kids.

But don't worry Philip, you'll have a chance to be violated by the Patriots on Sunday.
