When you pull on the joint you lower the pressure inside the joint quickly and the dissolved nitrogen in the fluid comes out of the liquid phase, forms a gas bubble and then pops. The fluid is then depleted of nitrogen and the joint cannot be cracked again until it re-accumulates.
This is basically the same process as happens to Scuba divers who ascend too quickly and get "the bends". The difference is that while the bends is dangerous because it involves the whole body, including the circulation, knuckle cracking is localized enough to be harmless.
