some fakeass made up korean gang in la crescenta, la canada, LA, cerritos, pasadena, garden grove, and la mirada. they got no balls whatsoever. starts shit and acts hard but just ends up getting fucked up by others. most of them are just lil kids that act hard. none are over twenty. always claims some OCF shit. CMS stand for corean menace society although others call them cock munching suckers. lol
