A penis whose primary characteristics are defined by it's
inability to reflect any perceptible amounts of light towards a
human eye due to its extremely diminished stature. Thus being
only perceptible by mechanically or computer aided viewing
devices such as a microscope. Micropeens are so small they make
me laugh.  I can't see your micropeen.  Apparently a micropeen
was on my leg, but I could not feel it. by G-Noles March 10,

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! by Earl
