All of die hard hoolingans hate cops, if you're one of them you should definetely go for this chant. A.C.A.B means all cops are b*astards, you should't say it loud, but listening to it isn't forbidden.
Those who stand here, Hate cops! Confidence is in us, I'm telling you the time will come! Once the day will come, When we get rid of them! A.C.A.B! A.C.A.B! A.C.A.B!
