A gang in the Hardcore Scene.
Short for 'Stand Your Ground.'
They are for the most part against girl moshers/dancers etc.
They like to start shit, and usually jump defenseless people, no matter thier age or gender, to show that they are the shit.
"Those pussies from the SYG are shit talkers, Theyre just white rich pissed off mommies little boys' that try to act bad."
SYG solidarity at its finest. grammatically correct, politically conscious, open-minded gentlemen who are willing to do whatever it takes, including beating the life out of "anti" narrow-minded kids who hate via the net. better beef than bail.
