When ugly girls think they are actually good looking or cute, due to the fact that they are easier to sleep with and less intimidating than hot girls. Therefore more guys are likely to hit on them and give them compliments to sleep with them. This usually results with the guy fucking them just because they are around while simultaneously raising the girls self-confidence. This is why so many ugly girls actually think they are good looking.
Girl: "Omg that is the first time I got turned down."
Girl: "Please don't fall in love with me."
.....don't worry your ugly no problem.
Guy:"Why is that fat girl wearing such a tight shirt?"
Dude: "Man she has got Cute Girl Syndrome."
