The delicate and intricate art of folding toilet paper over and over to maximise usage in order to avoid getting shit on your fingers. Practiced especially when there is a dearth of suitable bathroom tissue.
I nearly ran out of bog paper! Lucky I know some bathroom origami.
The "U" shaped yellow piss attain around a well used WC. It means any yellow stain on a floor but particularly around a water closet.
We will have to replace this flooring your majesty, the lino around the bog is like the queen mother's grin.
