Penis theory is a catch phrase used when a male person does something, says something, or just behaves in a certain way that is attributable to nearly ALL men. These actions and behaviors are usually pointless, without significance, or increase stress or work and most females would never act this way. This phrase is most often used in a negative aspect by females in response to these frustrating behaviors exhibited by men.
