Mines in a golf so it gets various names, the letter G means alot in my fam, we've been using it as an expression for something cool or cute or a term of endearment for a puppy or a small, cute car, I used to call my ex 'G'. My car is called lil-G. or super-G. it used to be the G-unit when it was in a polo but I decided that was too west coast us.
