Who is in charge anyway?

The recent blog discussion has got me to thinking... who decides what is "cool" and when it stops being cool.
We have discussed the fanny pack; once very cool, now not so much.
Then there are things like converse shoes, once very cool, then not, now cool again.
Words such as "bitchin". Once an extremely cool word, now if you say it, you are looked at like an alien.
I just wonder who decides this crap? And why do we give up things we really like to wear or say, because we will be deemed as not cool or out of style?
That's why I salute people such as Tony-C. He cares not what's "cool", but sticks to his own tastes.
I for one, try to stay up with the times, but every once in awhile I want to curl my bangs real big, spray them with hairspray, and put on my bitchin' straight leg pants, and go somewhere Killer.
But of course, I do not. I have fallen slightly into the trap of society acceptance.
Which kind of bugs me, but it does save alot of grief from others as I have witnessed as of late................
