Brixton

Brixton was a district of London on Earth.

Drax was caught engaging in criminal activity to procure replacement parts for his TARDIS, and served a jail sentence in Brixton as punishment. During his stay Drax picked up Brixton's local "lingo" in order to survive, and the resulting accent and idioms remained part of his speech patterns even after he left Earth and resumed his travels.
