SG* is a person who thinks they are really cool and gangstar but they really aren't. Basically, they are posers.
That person thinks he is so SG*.

Pronounced, "Es-Jee". A common term for a "Silly Girl". This term refers to a female, (or a male who has femanine hair) generally a blonde, whio is intellectually incapable. This person typically stares off into space quite commonly, and procrastinates on homework. A typical SG will believe themselves to be "Ninja", or significant in any other way, but they are most definitely not. "SG's" make terrible friends and are usually jerks to the people who are nicest to them. Good type of person to make fun of.
