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?

STG 

STG, is a group of unorganized, disrespectful mobtards that play myspace mobsters! They often use foul and vulgar language on other players pages.

STG members have no honor and will brake stand downs, also partake in other shameful acts. STG members have no pride and should be put in a Mobster Hall of Shame!

STG is a mob of 85 Active people, but we call in 5 allies and beg the Irish to help us fight a mob of 20!

We will kick out mob members of no reason, we will just say they were spying in us!

When stand downs are in place, we will let two days go by then attack again. Why honor stand downs?

We will talk foul and vulgar on peoples pages and make mom jokes..
