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.
The Red Kangs greeted each other [they called it How You Do] with some sort of children's clapping game . (DW: Paradise Towers)
- The name is a phonetic corruption of "gang".
