Sweat, dampness, wetness (from perspiration or anything perspiring) of the grundle area. It is a pandemic that has afflicted many people. The supporters of SGS have planned a 10K benefit run/walk to support research and the potential cure for SGS. Currently, there is no cure, but there is hope. Treatment for SGS symptoms and breakout can be implemented through the use of an applicator tip.

Also known in the mongering world to be a "street girl" or prostitute. One that performs sexual acts for money that is a girl. (There are other words for ones that are not ACTUALLY girls) Less likely to have GFE with a SG, but more likely to get a BBBJ from one then one that works in a bar and or stripclub.

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

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.
That SG be actin' like a fool...

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.
