Fine young thick chicks with big a ole' onion booty and sexy smile. Sometimes located in the yaoi section of a local bookstore or In Walmart at 3 am wearing cat ears. Occasionally they travel in packs of large numbers containing at least 1 other Phattygirl of a "morbid size" and a small group of young malnurished males whom are unsure about their sexuality and live off a diet of Happy Meals and their mothers Valium.

PhattyGirls love taking profile pictures for Facebook In which they are blowing a imaginary kiss to their favorite anime hero.
Man I was at the CosPlay convention last week, there was PhattyGirls all over. I'm taking one out to the Golden Coral before the ICP show.
