A two letter phrase that stands for "so good". Often used sarcastically when someone does well on something to make them feel awkward or when someone does really bad on something, again, to make them feel awkward.

Get the SGmug. A Gibson guitar that could be described as the poor man's Les Paul. Stands for "Solid Guitar" even though it's light weight and thin neck make it very prone to accidents (like headstock snapping). The most common setup is mahogany-bodied, cherry red in color, and two humbucker pickups.

1)
A group that roam the area of east sydney. They think they own the streets and the entire network or "league" as they call it.
Rumour has it, that much like the Universe, SG was created with a "Big Bang", this is officially named the "Worm Fart". Which upon release has the innate property of raising the level of dopamine in all SG members within it's radius. Inducing a freedom ritual.
They have a multitude of gang signs including the straight face, the freedom totem and the notorious SG symbol. These however always hold an aura of transience. The greatest example of the continuously changing nature of these greetings is the SG fistbump. There are currently two acceptible fistbumps including the untouching walk-away bump and the rock v paper bump. Both derived from the youtube-famous JimmyTatros.
To become a SG member, the individual has to attend the freedom initiation ritual which is held in one of the founding member's crib. Every one of SG's rituals are somewhat confidential and there is currently no solid eveidence of them ever happening.
These scandalous people believe that they are hardcore but in reality they are just a Study Group.
2)
An ambiguous reference to commentate the general emotions felt after any game or match played online or in real life.
It can stand for Superb Game
or Shit Game.
