In a survey conducted in 2000 by Kimberly-Clark, it was found that men prefer to fold their toilet paper, and women like to wad it

On the other hand, there are two choices of orientation when using a holder with a horizontal axle parallel to the wall: the toilet paper may hang over or under the roll. The choice is largely a matter of personal preference, dictated by habit. In surveys of American consumers and of bath and kitchen specialists, 60-70% of respondents prefer over.

Also, you can make some Toilegami which refers to toilet paper origami. Like table napkins, some fancy Japanese hotels fold the first squares of toilet paper on its dispenser to be presented in a fashionable way.
