A Catalano Complex refers to the high
likelihood that
consensual sexual actions have taken place or will take place at least once between too siblings, provided that:
Both siblings are considered highly attractive by the majority of their peers, and:
The
age difference between the siblings is relatively small.
The strength of the Catalano Complex between two siblings has a positive
correlation with the siblings' average attractiveness and has a negative correlation with their difference in age. This is due to the following reasons:
There would likely be less sexual attraction between the siblings if one or both were generally considered
unattractive, and:
The larger the age difference, the less likely it is for both siblings to develop sexual attraction for each other at the
same time. Also, the larger the age difference, the less likely it is for both siblings to feel comfortable with the
sexual relations in question.
Person 1, looking at a hot girl talking to her equally hot
twin brother: "Damn, they definitely have a Catalano Complex."
Person 2, in response: "Hell yeah, the
incestual probability between them is
high as fuck."
