Millimeter Peter, also known as your local drug dealer, is defined as the smallest pecker known to man. You can find one of these if you look around the corners of your city! You can usually find one by homeless shelters or in some random woman's mothers house!
"Never thought that he'd have a millimeter Peter!"
"I was so disappointed when his pants came down and in all his glory, a millimeter peter stared back at me."
