first, i think it feels REALLY fucking good... many different people have given me many different answers.

what can you pop??

fingers=7 different directions
thumbs= 4 different directions
tailbone= 2 different ways (each leg)
neck= by rolling my neck i can get like 3 or 4 good releases of pressure
ankle=4 different ways
wrists= 8 different ways
elbow= 2 ways
knee= 2 ways
back= 5 (not just 5 pops, 5 ways to get my spine to pop all the way down)
hip= 1 way
shoulder= 2 way
jaw= it pops every once and a while. involuntarily. i hate it when my jaw pops... it makes me shiver. it hurts like hell too.

i think that is it. my hip/shoulder i refrain from popping.

You can crack your penis by applying pressure to the base if you wake up with an erection. I can only do it when I wake up with one, same with others I have talked to. Anyone who can crack their penis any time???

I have TMJ so my jaw always pops and hurts.

I can get five or six good cracks on my neck. Really loud. But I have to use my hands to jerk the neck sideways.

atomic,

yeah, i did that twice.... it doesn't feel very good... thats why i didn't post it...

ack. tmj is a bitch.

you missed out toes..

although it's easier to get someone else to do them for you

I've always wanted to pop my penis. i'll have to remember to try. Usually at the end of the day i can pop out my ankles. I like that feel. Also, once every couple weeks or so, i can pop my sternum. Sounds kinda gross when i do it, hurts a little bit, but it feels damn good when it's over. First time i did it it hurt like hell for a while.

i can pop my toes really easily!

i can also pop something els, but that aint bodyparts

that's right... d'oh.

toes... hmm. 3 different ways.

My Back all the time it's really loud too, I need to exersise more. I used to do the fist cracking but I stopped I can still do it though, really intimidating

almost forgot...

cause of all the powders that went into it, i can pop my noise alswell, but really softly, and only from time to time. i can do this cause my noise bone has kinda been eaten half away away
ah well, you only live ones!

I often crack my neck by turning my head as well as crack my knuckles with my opposing hand. I occasionally reach out and crack my back by leaning backwards while stretching.
