What is it about my deodorant?!

Camille's latest pastime is sneaking into the bathroom, retrieving my deodorant, and, if I don't intercept her in time, doing one (or more) of the following:

A)  Hiding it.

B)  Removing and replacing the cap so as to take large chunks out of it.

C) Smearing it on things.

Why is this?

and, more importantly,

When will it stop?
