Man Ruler

A ruler that for every inch beyond 5 inches, the actual length of each segment shrinks by half, leading to a severely exaggerated final measurement.

It is the most commonly used tool when a man measures his manhood.

Whether made with a physical measuring tool or a perceived one, the measurements are always equally exaggerated.

John: "Yeah man, I've got a huge tool!"

Pat: "Is that so? I have my doubts."

John: "NINE THROBBING INCHES BUDDY!" *unzips fly*

Pat: "I see you've been using the Man Ruler again."
