When you run up on your boy for chatting bare shit and lay him out next to the £1.50 cabbage at Tesco's , then when you finished dragging your fat nuts off the homies face, passed the carrots and ask that fit thing at the self checkout for her number that's when you know, it's GSO . Gang Shit Only.
