A retarded English Communist prick who doesn't realise that the Soviet Union is gone and the class war is over. He also lacks the ability to spell or to write grammatically, thus betraying his roots as a piece of pikey scum.

Black Flag wanks a lot about the glory of the English working class of which he believes himself to be a member... He sadly doesn't understand that in order to be a member of the working classes, you first have to, y'know, actually have a job.
Black Flag lives in a council flat in Bristol and relies on the tax-payers' money to provide for him and his squad of fifteen illegitimate children. Without his giro, his kids would starve and he'd have to give up his heroin habit.

The black flag nation or bfn is a group of faggoty teenagers in Murfreesboro, Tennessee, who think they are all cool and edgy because they are anarchists. They don't have members across the U.S. or Europe or Asia. No one from any government agency has ever investigated members of their group, because they don't do shit. Any crimes on their records probably aren't any worse than jaywalking.
P.S. their grammar is terrible.
