Is there the slightest possibility in this world that the word "kidult", meaning basically teenager, existed before the beginning of the current millennium? Such that it might have been used in, say, an internal memo from the BBC in the mid-seventies?

I'm pretty sure that this is not the case. If it is, then either I've jumped universes or the aliens got me again. If not, it just means that a book which purports to be non-fiction is in some part invented from whole cloth, which is disappojnting but liveable-with.
