@anya i was punched in the neck and now my neck pops randomly and involuntarily trust me i know the feeling. just be glad it's your elbow and not somewhere worse like a neck...
Hey, I'm pretty new here too. My one joint that consistently pops is my right thumb. I can pop it multiple times per minute, and I've been able to do that since I was young. Most of my other joints pop as well, but my thumb is the only one that I can pop that often.
I know this reply might be useless since the post is so old, but I would think an elbow crack would be the most impressive. A nice slow lock and pop. Looks cool too.
