Crown is generally referring to the grain of the wood. Look at the end and see how the growth rings are going. You want the crown to be up, the high point of the curve of the rings. Looking down the length of the board it may be bowed one way or the other. This can also be called it's crown.
The reason to do this is that if the board is going to warp or cup, it will do it the way the rings go. If the board is exposed to weather, the edges will curl up and it will hold water. If you put the crown up, the water runs off.
