I think Bruce up top there had it right on the mark

"...the "stubble look" was little else than a ploy on the part of a few lazy, overpaid "stars" to justify their own sloth. "Hi! I'm A)Don Johnson or B)Brad Pitt and I've just been too f***ing lazy to shave for the last few days. But, hey, I'm a superstar, so instead of 'laziness' will call it a, uhhh, 'fashion statement'. "

Any time I see it, the overriding impression is - "Idle tosser can't even be bothered to shave."

In the immortal last words of Julius Caeser "TEE HEE Brutus!" LOL!!
