Little plastic bracelets worn by people on their wrists. Some people say that emos wear them to cover up where they've slit there wrists. Some people say if you snap one you have to do something sexual with the person who is wearing it. Thats total crap. Theyre just bracelets.
Loads of mine have snapped, simply because I play with them and chew them.
Boy snaps exited girl's jelly bracelets:
Girl: Now guess what you've got to do to me!!
Boy: Buy you a new one.
