An individual, whom, by the subjective generalization of the observer, has never been exposed to much stress or hardship and appears to have had academic, career and personal success that is far above average. The individual has an extroverted personality and feints an image of egality with respect to his or her peers. The individual will be well respected in his or her career and other activities and is usually very physically active in aerobic athletics. The quality of the material objects that these individuals own are usually superior to any alternatives.
The prick portion of the person's personality is realized due to minor fluctuations of the demeanor that may appear to exhibit the same qualities as bipolar disorder. The observer will understand the minor fluctuation of the personality to be due to having a life with very little exposure to stress or hardship and the brief harshness of the fluctuation is akin to that of a pin prick, hence the name 'prick.' It should be realized this an over-generalization of the observer on the individual and not a scientifically accurate method for analyzing a personality.
That guy in the BMW just flipped out because the window washer missed a spot, what a prick.
