I started cracking my knuckles in 4th grade or thereabouts, which led to cracking pretty much every single other joint in my body to this day. It annoys the hell out of my mom but I can't help it either. I'll just absent-mindedly crack my knuckles, elbows, toes, etc in front of her and I always have to apologize immediately after I notice how POed her face looks lol. I love doing it though. Always feels so satisfying when my knuckles or back pops and especially when my wrists pop omg those are my favorite.

It's apparently a "bad" habit but at least it's not smoking or drugs or anything so... *cracks knuckles*
