gg 

Generally used to express a form of joy. "gg" comes originally from the warcraft 3 scene and means "good game" and was often ironically used. Some german guys adopted a more general meaning to "gg" or "sehr gg" (which means "very gg")

gg, we just smashed that team hard.
I got a new car, sehr gg.

gg 

A very attractive woman that likes to throw down and get sideways, also known as a (gg)good girl. Other letters can be added in front of gg to depict what kind of good girl, ie. cgg could mean cougar/crazy good girl or vgg which would be very good girl. Combinations are the users choice

So many gg's, so little time.

You should have seen the cgg that took me down last night, I have bite marks.

Dude, that dgg (dirty good girl) asked for it in the anoos, I had to say yes.
