all the beautiful bobs

So now that bobs are all the rage agian I was wondering how many types and variation there are and can we name them.  I know there is a beveled and a graduated and an inverted I hear rumors about something called the five point cut and the box bob but I dont know what else.  I am also interested in this new bob rage where the hair almost looks like a bowl cut.  Is this still considered a bob?  LOL hope everyone else has as much fun pondering these seroius questions as I do=)
