Sneddin
Unemployable "Wayne and Waynetta" types (of Harry Enfield fame). People of no ambition, sometimes overweight or with young children in tow. Unaware of healthy eating, rarely eat fruit or vegetables - often found with food stains on their clothes. Love Pizza/ Kebabs. Talk loudly, sometimes shout in public, but generally not violent/ dangerous except for the minority who have badly controlled dangerous dogs. Not to be confused with Chavs - who can be intimidating. Possibly a North London term as this is where have heard it used (Edmonton Sneddins etc).
Looks like property prices are coming down - there seem to be more Sneddins around these days.
