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.

Get the SGmug. Single Guy Syndrome: It causes incessant rambling (from the affected) usually about things that the listener doesn't care. The best treatment for this condition is to just be polite and listen.
It's pretty clear he has SGS, he keeps ranting about his boring previous jobs, probably because he doesn't have a significant other to listen to him.
