A complex that
inevitably consumes hot girls given the extra social leeway, gifts, and attention they receive throughout their lives. This goes to their head resulting in a distorted view of how important they are.
This directly relates to the hot-crazy scale and is generally the cause of the crazy axis of the scale. The hotter a girl is, the crazier they get because of society's unbalanced feedback towards their behavior.
The sad part is that
inevitably, a girl's
attractiveness will fade with time, but the mental damage caused by hot girl syndrome has already been done so you're left with an ugly, crazy woman long-term.
"Wow, that girl's at least a 9.5!
I'm going to ask her out."
"Be careful man. She's hot, no doubt. It's highly unlikely she doesn't have
hot girl syndrome. You really want to
deal with that much crazy?"
