A Fat Girl Injury is an injury that someone has when doing something purely out of hunger or thirst. The person doesn't necessarily have to be 'fat' or even a girl. There are different types of fat girl injuries, one of these is a second degree fat girl injury.
Fat Girl Injury - I was so hungry for soup and it was in a hot bowl, instead of putting it on the table, I put it on my lap and got 2nd degree burns.

2nd degree Fat Girl Injury - Lets say me and my friend sit down for dinner and we're both really hungry and while I reach to grab something, he stabs me in the arm with his fork.

Fat girl Syndrome refers to the inflated self esteem of fat bitches. They always portray themselves as much more attractive than they actually are in real life. They often wonder men don't want them, as they blindly acknowledge their weight problem. They often brag about the amount of guys that talk to them (usually only on social networking sights where myspace angles are used to the fullest. See "myspace angles" ). But really, the amount of guys that actually talk to them in real life are proportional to the amount of weight that they have "supposedly" lost since last summer. i.e. not shit. BEWARE, if you give any attention at all, they will assume your friendly actions are actually sexual advances. DO NOT! I REPEAT! DO NOT ASSOCIATE YOURSELF WITH GIRLS SUFFERING FROM FAT GIRL SYNDROME!

"When a bitch looks like Precious but think she looks like Rihanna; a linebacker kind of bitch that should be blocking for Miami, not dancing in the club."

When you dance up on a fat girl, make it seem like your interested. Then grab on to her and tell her what a fat dirty bitch she is and see how long it takes her to buck you off

A Profile picture (Social Networking Sites) that is strategically positioned so you can't quite tell weather the girl in the photo is good looking or ugly or if shes fat or thin. Most people that have these profile pics are fat and ugly.

Person 2: Is she good looking ?
