(-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?
