In the front indicates a small penis size, in the middle indicates a medium penis size or good sanitation after using the toilet, and on the back indicates a big penis size.
This method works for mosts toilets, and is considered solid proof.

When a man takes an old wooden ruler, and smacks his girl on the ass such that the protruding/indented inch marks on the ruler are imprinted to the girl's ass. Then the man measure's his cock on the ass imprint (before fucking the girl) while she looks in a mirror, so she can see exactly how much she's going to get and prepare accordingly.
Use in a sentence: She asked me how big I was and I replied, "bend over and I'll give you The Ruler."
