Fg literally means "Friendly girl", it can be used in a variety of situations where one may want to talk about a girl but without actually referring to her directly, so the term fg may be used. Fg also has a double meaning now this cant be defined for it is for you to discover... the antonym (opposite) of an fg is called a "ufg" which means un-friendly girl (this has a double meaning as well)

Example 1

Guy 1: Woah! That girl over there is an fg!

Guy 2: Yeah man! Can't lie!

or

Guy 1: Do you think that girl is an fg?

Guy 2: Well sorta... Could be better

Example 2

Guy 1: Awww wtf?! That girl over there is a ufg!

Guy 2: I know man, she disgusts me!

or

Guy 1: Is that girl over there an fg?

Guy 2: Nah! Shes more like a ufg.
