Kang
From Tardis Wiki, the free Doctor Who reference
The Kangs were gangs of wild young girls living inside the Paradise Towers. They were divided into groups by at least three known colours: Red Kangs, Blue Kangs and Yellow Kangs. The last Yellow Kang was killed shortly before the Doctor arrived on Paradise Towers. (DW: Paradise Towers)
- The name is a phonetic corruption of "gang".
