A group of friends who got together to watch each others backs or be there when they needed help. Some consider it a gang but its much less violent then a gang. Southridge Sproof started in Mesa, Arizona. It first started out as a joke untill more friends got interested in it and put more time into it. They arent known to start violence but if violence comes to them they will be sure to return the favor.
Person #1 "hey man you heard of that underground group Southridge Sproof?"
Person #2 "Nah, what are they all about?"
Person #1 "I heard its a pretty sick group of guys who always got each others backs and like to organize cool shit to do"
