FGS is when fat girls think they can compensate for their apparent lack of sex appeal by going overboard with a "quirky" (i.e. annoying and trying way too hard) personality. Even if you were once a fat girl, but have lost all the weight, you can still suffer from FGS.
Look at her! She is so different and unique. You can bypass her oozing rolls because her personality is so interesting and she is so weird but intriguing. Dumb bitch has FGS.
