Will cracking your knuckles really make them swollen?
I hate to hear other people crack theirs, and I usually yell at them for doing it. My grandma would have yelled and added a bit of advice about when you're her age and what's going to happen to you. Sometimes I tell people it's not good for them. But I really wonder sometimes, if maybe it's not bad at all but we just hate hearing that noise so much (crack, crack, crack) that we made up a reason to tell people to stop doing it.
What's the deal with the word crack anyway? Think about it: what did crack ever do to you to deserve such a bad rep? Crack. If people have fun hurting themselves, shouldn't we just let them do it?
Crack.
The more you hear it / say it / type it, the weirder it seems.
Asscrack.
Crackwhore.
Crack.
