Identical Twin Theory

The idea that two semi-attractive females have an increased sexual desirability due to being identical twins. (It is similar in concept to the cheerleader effect).

Guy 1: yo check it out hot twins at our 9 o'clock. I'd do 'em.
Guy 2: you mean those two semi-ugly bitches? hell no!

Identical Twin Theory in effect.
