Fat-girl 

Slang used by British soldiers during World War 2. A fat-girl is ahooker, whore, tart or prostitute. She may be an enthusiastic amateur, but she takes money for making the beast with two backs.

I was out on the razzle last night and had a knee-trembler in the park shelter with a local fat-girl.

fat girl tits 

Tits on a girl that are huge, but only because she is obese. Because technically they still are "Big Tits", girls with them still think they are hot and usually brag about them whenever they post a personal ad. Same as calorie tits.

"SWF, 36 with ample chest"

Typical ad from a girl with fat girl tits.

Fat Girl Confidence 

The undeserved, but ever-present, condition of self-esteem felt by fat girls who believe that men actually care about "personality." Brought about by Chubby Chasers trying to score by laughing at unfunny jokes or listening to terrible poetry. See also, Freakhog (3)

It's that fat girl confidence, man, it can't be deterred.

Fat Girl Sauce 

Ranch Dressing

A dipping sauce ordered with every meal by every fat girl ever. Breakfast, lunch or dinner, chicken strips, pizza, a side salad, or carrot sticks, it doesn't matter how healthy or unhealthy a dish is, a side of fat girl sauce is a great way to add a few more calories.

Fat girl: Can I have a side of ranch with that please?
Waiter: (Whispers to self) One side of fat girl sauce, got it.

fat girl at a Dairy Queen 

An alcoholic beverage made from equal parts of Bailey's, Creme de Menthe and Sambuca.

I ordered a Fat Girl at a Dairy Queen from the bartender, but he couldn't make it as he was out of Sambuca.

Fat Girl Syndrome 

A variant of Ugly Duck Syndrome. The girl was fat as a child, causing them to to be starved of male attention. When they grew up, they lost the weight- thus becoming hot. As adults, they either become super sluts- even sluttier than normal sluts in order to compensate for their lack of male attention when they were younger; or they display shy behavior with a great personality.

Male 1: Oh My God...is that Bianca Marshal?
Male 2: Yep. She lost 72lb since high school. She's f$!king hot now.
Male 1: Daammmnnn...I always used to make fun of her in class. I wonder if she'll let me into those jeans since there's a whole lot more space.
Male 2: I doubt it. She can hardly look people in the eye while talking.
Male 1: So basically, she's got UDS?
Male 2: Not exactly, I like to call it Fat Girl Syndrome.
