(Pretty Girl Disease)-A common ailment among attractive women. It's where attractive women don't have alot of friends cause other women hate on em all the time and dudes are intimidated to approach or just wanna bang. Alot of the ladies on this site will disagree because they have never gone through this, (i.e. NOT "Pretty") but for the chosen few who do know about it, it is very real. I used to use my knowledge of this type of situation to prey on the finest women by tricking them into thinking I am not interested and just wanted to be friends then....GOTCHA!!! For the other dudes who; like myself, would like to benefit, the process can take a while, so make sure she is fine enough to be worth the time. The worst that can happen is you end up with a beautiful girlfriend/wife.
PGD can leave a beautiful woman alone in life forever.
