Israel claimed that he had a big cock, but when Sarah tried to blow him she realized that it was only 3 inches, she then exclaimed, Israel you are Mr. Tiny Dick. Israel was Mr. Tiny dick because he thought he had a big dick, but is was only 3 inches long.
An extremely small small dick. Something that is so small it can't even be seen by the strongest telescope. So small that it would always win any tiny dick contest.
