This could be cavitation. Here's an article on it (Is The Crack In Your Neck Worth It?).

When you twist and bend your neck, you stretch the joints. Inside each joint is a liquid called synovial fluid that contains gases like nitrogen, oxygen and carbon dioxide. This liquid exerts a certain amount of pressure against the ligaments around the joint (called the joint capsule). The stretching causes the pressure inside the joint to drop. When the pressure drops, the ligament gets sucked into the joint and a bubble of carbon dioxide forms. The formation of the bubble creates a popping sound as it comes out of the synovial fluid (cavitation) and increases the volume of synovial fluid temporarily (by about 15%). The increase in volume pushes the ligament back into place creating another popping sound (these occur so fast you hear only one sound). You cannot repeat the snap, crackle, pop for about twenty minutes or until the bubble dissolves back into the synovial fluid.
