acrynom for Grow A Pair Of Balls. used for people that are cowards that can't fend for themselves when they do something messed up.
use it when some dip wad throws something at you or you're friends and cant defend himself. then when you are gone he corners you're friends just to get at you. like really. gapob and fight me, not someone that had nothing to do with it.
