I really had no idea what might be found outside the gates when they opened: Mobs of jumped-up slines rushing in with pitchforks or molotovs.

Short for "baseline", a sline is someone with no marketable skills or useful knowledge nor hope of acquiring same. Essentially, a normie that has no hope of improving.
