What is the most common cause of piston slap?

“Piston slap is generally caused when the cold running clearance (piston-to-wall clearance) is large enough that when the piston rocks from side to side in the bore it “slaps” the side of the cylinder and causes noise,” explains JE Pistons’ Clayton Stothers.
