Short for micro penis, but is used to describe someone or something that is lame, goofy, or just a straight up douche bag.
That person who just drove by me in that Honda civic with the overly loud exhaust system is a total micro peen!

a very small penis peen could only be seen under a microscope. Most women don't enjoy the so called micro penis.
