Western Pennsylvania Curse
The unfortuante series of events when a really attractive girl is spending time with/ hooking up with a really unattractive

guy. This situation is very easily seen in western pennsylvania, thus the name. Statisticians indicate that 64% of girls between the ages of 18-24 suffer from the curse. There is no known cause for the curse, only that doctors and psychologists point to major brain damage suffered at birth, probably caused by fetal alcohol syndrome.

I know man, its that western pennsylvania curse.
