Noun, A person who exhibits such an amazing lack of common sense, you wonder how they even have the brainpower to run even the most basic autonomic functions. Small rodents and credenzas have an intelegence greater than the average peen. (Note: if you know what a credenza is, you, by default, are NOT a peen although it does not make you immune from exhibiting peenish behavior)
On the surface, it seems that many people on Earth today are peens but the title of peen is reserved for those special type of people that invoke an uncontrolable urge to yell or to hit people with sticks. In the United States, it is still illigal to kill, maim or otherwise harm peens although there are some that suggest that if being a peen was painful, people would avoid exhibiting peenish behavior.
Related words:
Peenish and/or Peen-like: used when someone isn't atually a peen but they are exhibiting behaviors that closely resemble that of peens.
