I asked Dermot and Dave what they thought a WOB was.
Dermot guessed "Wife Of Basketball player" and Dave's eyes glazed over.
A WOB is (apparently) what we should all be after this season.

It's a wavy bob!!! DUH!
It's all the rage in... eh... well, on JLaw's head anyway:
Tons of other celebs are rocking it too.
Get booking your hair appointments, ladies, Christmas is coming!!!
