Phrase used to describe a male penis when it is so short or small that it can only be measured in centimeters.
1. Brett Favre's Penis
2. NYJets football player: "Hey Favre, my 5 yr old son's Johnson is bigger than your Centimeter Peter!"
The word centimeter peter comes from Scotland where a young boy name Peter was jacking off. He realized that his penis was really small so he came up with a nick name for his penis. He wanted it to rhyme with his first name. Hence the name Centimeter Peter.
Brad you have a centimeter peter.
