There is a thing where deranged people are trying to use the same hygiene products as their celebrity crush, because smelling the same way as they do makes them feel like they are living together or some shit. That's on about the same level of mental illness as being a unicorn, so better not to think about it too hard or you risk becoming like them
I did consider it coudl be something like this, but was willing to give people the benefit of the doubt and put it down to mindless consoomerism rather than being completely deranged. But no, you're probably right.you get a wig, you shampoo said wig and you put it into your bodypillow. Do you get it now?
