That feeling when you don't get your daily dose of pornography, and start to go mentally insane because of your lack of horniness.
Basically, when you haven't seen actual pornography for a long period of time (usually 24 to 72 hours) and you start to get upset because you haven't seen breasts or cocks, or other body parts in days.
People who have been depornified for months and/or years tend to become more mentally stable after not looking at porn for such a long period of time, and they finally end up socializing with others like a normal functioning human being.
