Map of London Gangs (opens in new tab)

"They beef 1011, Original 3rd, Purple Hayes and West Drayton. They throw up W's, B's and add K's to their opps"

Can anyone translate this into English? I'm guessing "they beef" means "they are in conflict with".

What is the first action to take if the gang has taken interest in you? How do you evade them and roam around freely in other parts of London?

This looks like a whole lot of larping.
