Gelly Braclets.

Okay question.
What do each different gelly braclet colors mean?
I wear a whole bunch of them. Like I think im up to a 140 and and everyone is always like 'don't they mean something?' and im just sitting there like I don't really give a flying fuck thinks very much. But I kinda would like to know what each color stands for I know they are "sexual favors" and whatnot and im just not into that and because im not going to whore myself out to random guys who break bracelts off of my wrist.
But that's just mee.
Thanksss
