An academy in London appears to have banned students from using slang words in an attempt to crack down on the use of urban language.
Many have taken to social media sites in outrage at the news phrases and words such as "you woz", "bare" and "innit" will no longer be tolerated at Harris Academy in Upper Norwood.
The institution is one of 27 academies and free schools in and around London sponsored by the Harris Federation.
The school has seemingly put up signs with a list of "banned words," which was posted online by one disgruntled Twitter user.
Labour MP for Tottenham David Lammy defended the move, only lamenting that "sup blood" was not included.
