The easiest way to calculate unpopularity lies in the proximity contest. Pick a guy, and calculate the amount of space which separates him from, say, a girl. To figure the unpopular quotient for girls, just look at one, and figure out if you would like to keep looking at her. The number of seconds it takes before you tear your eyes away, multiplied by the time that she cares that you are gawking at her breasts, will give you her unpopularity rating.
