look up any word, like lemonparty:
 
1.
GBZ
The seat in between two guys at the movie theater, otherwise known as the Gay Buffer Zone.
Dude, move over one seat! We need to create a GBZ!

2.
GBZ
Ghetto buffer zone. This is the section of town that is not quite in the ghetto but certainly not good enough for you to leave your car unlocked. A little shady but a little urban chic.
Dude, that apartment is sick but it's in the GBZ and I'm afraid my rims will get lifted.
