STG
Aptly stands for 'Super Tan Girl'; a combination of a Gina and Valley Girl into one entity. Usually blonde, but is based on the overexcessive and obvious fake bake the girl has undergone.

Also associated with the more popular crowd, but not necessarily meaning that they are.
"Do you think that she went on vacation?"
"No, she's just an STG"

or

"That girl over there is such an STG"
"tell me about it, she could support the whole bronzing industry single-handedly"

stg
(-noun -abbreviation)
stg stands for 'small tits girl'. Generally used to describe a female person (or virtual character) with small-sized breasts.

The abbreviation can (relatively) safely be used among friends in public places, without raising suspicion of the person in question.

(First seen being used in source-code of some game as a reference to a female npc)
person A: Hey, you see that stg at 3 o'clock?
person B: That blonde? Yeah, so?
Person A: She's cute!
Person B: Dude... why do you always go mental about planks?
