"Northerning it" or "I've northerned it" are terms used once one has made themselves sick through consumption of too much alcohol. The phrase originated in 2004 by two Nottinghamshire holidaymakers in Ibiza. Use of the term became commonplace once they returned home and it began to be used by their friends. As a result the term has now fully established itself in the region through word of mouth. It's influence is spreading and can now be heard all over the Midlands and in some areas of Yorkshire.
The term itself has developed to its current form gradually over the last three years. The phase was originally created after they witnessed someone soil themselves in the Ibizan hotel Es Calo Playa. The holidaymakers found this hilarious and they developed a traffic light system to judge the various stages of soiling. The individual who has fully soiled themselves was judged to have scored red and the term "redded it" had been born.
Obviously adults soiling themselves is a rare occaisson so the holidaymakers decided that they would class any soiling incidents as a "southern" e.g southern red, amber or green. Far more commonplace was witnessing adults making themselves sick through alcohol abuse and the "Northern Red" phrase was born. Over time the phrase has been abbreviated to "Northerned it".
Pedro: Alright mate, youve been a while in the toilet? Have you northerned it or been for an organised southern red?
Magma: Yeah I northerned it.
Pedro: Ah right, do you want a chuddy?
