where can I find rules on props

Is there any kind of site that has rules for the props game Neagreanu mentions in his latest blog?

Or is "props" just basically a made up series of bets by the participating players that always varies?

Sorry is this sounds dumb but I would really like to learn how to play so I can liven up my home poker games.

A "prop" bet is basically a bet on anything. In poker, it's usually a bet on what number the cards are going to be, what color, what suit and so on. There is no game called prop bets.

If you look at the "Danny Playing in the Big Game!" thread in the WPT/Television forum one here, one of the posters answers a similar question; describing those props in some detail.
