Larry and AeroBaron have done a good job describing piston slap. On your diagnostic question, if you pull the plug wire from the offending cylinder the knock should get louder (whereas if it's a tappet noise you shouldn't hear a change). Piston slap is fairly distinct (metallic but more hollow sounding than tappets) and almost always louder when the engine is cold. Someone who has heard it before should be able to recognize it.
