A fat girl that would be flat chested if she were skinnier but has "tits" only because she is overweight. Based on her fatness, if she were a guy, the same "breasts" would appear. The Fat Chested girl is totally oblivious to the fact that she doesn't have actual "boobs" and stops at nothing to show off her "jugs".
"Daniella pleeeaaze, you don't even have tits, you're just Fat Chested. If you dropped forty pounds your chest would look like my little brother's back."
It's the font color used in an AOL chatroom by a typically ugly and fat girl, who wants to appear that shes cute and sexy.. usually accompanied by a screen name such as "HottAngelMami"
HottAngelMami: like omg im so hot, dose u wanna see mah pics?
