It's the release of synovial gases that reside inside of the joints. The synovial fluids and gases are essentially lubricants for joint movement. The popping sound is like a bubble of this gas/liquid bursting. It is actually not harmful or damaging in most cases.

It wont make your knuckles larger, but you might make your grip weaker if you do it too much cause it can start causing problems, such as arthritis.

Does anything happen when you crack or pop your knuckles a lot?

They used to say that cracking your knuckles would give you arthritis. A doctor friend of mine says that that is not true; that "popping" your knuckles is just releasing gasses in the joints. However, the danger with cracking your knuckles is over-extending them or flexing them too far, which could cause pulled muscles or eventual joint damage.
