Mostly, made-up.

Sadly, there is a long history of realizing that using make-believe or nonsensical words creates a lot of confusion, because it's undefined and inconcrete; dante's submission, "sexualization," literally means "you made them sprout genitals" - presuming they were a real-life marilyn manson asexuality suit previously.

But, it does tie into a lot of things. One is race...

Recently the article said "She used sex toys to groom the children"

...a world terrified that white girls will use their human worth to their hairbrush, while a little black girl really will suck your dick if you do her braids.

...and the other is... primatology, and the stress/antistress response, by which it equivocates to "this prevents and ameliorates child abuse."

But... mostly, it's a made-up word - and the only party ever convicted of grooming someone for sexual abuse was, in fact, a hairbrush.

...although I hear the electric toothbrush is making a close second.
