Scrubbing/brushing your teeth with a towel to clean the plaque off your teeth. Known as British due to the stereotype of English folks having yellow/white teeth which is the usual result of a British Scrub.
Nigel your teeth are mighty yellow, perform a quick British Scrub in the bathroom before your meeting in a few minutes.
