Sunderland is a city in (the county) Tyne and Wear, in the North East of England.
People born in Sunderland are known as Mackem

Possibly known for their poor football team, SAFC.
Most likely if any Mackems view UrbanDictionary, they will give this entrant a thumbs down solely because of their embarrassment and pitiful denial of being scum.
