There used to be a great Wikipedia page on it, but the deletionists got to it at some point and turned it into this content free page http://en.wikipedia.org/wiki/Cold_chill

There's also a reddit devoted to it http://www.reddit.com/r/frisson but I've found that what causes one person to frisson doesn't necessarily cause another.
