In the city of Liverpool, England, Plastic Scouser is a term used to describe a person who sounds Scouse but lives on the other side of the River Mersey to the city itself. Usually people in Birkenhead, and Wallasey are referred to by this term.
'Plastic Scouser' can also refer to someone very proud of, and quick to emphasise their supposedly 'scouse' heritage, despite living in a town that is not part of Liverpool. Not necessarily a town on the opposite side of the River Mersey from Liverpool.
Sometimes, using scouse slang, the phrase is shortened to "Placcy Scouser". Placcy being pronounced with a hard c, like Wacky.
