Ikr. It's so weird why... It doesn't really sound *that* gross. Also have you ever cracked your knees? lol
Neck, knees, wrists, back, toes, ankles, knuckles. Basically if it moves I pop it...And it's heavenly.
my elbow cracks a lot. when I stretch it out and it's because I put so much strain on it when I go rock climbing. the two bones in my wrist graze against each other xD
