A swill is someone from Swilly, who thinks they are solid walking around with their burberry scarfs and baseball caps. They have their adidas trackies tucked into their football socks, and say things like, "ere, don't mess or i'll ding ya, 'n' run u over wimme nova!"

Someone who comes from Devonport or the area round it, and reckons they're the hardest person to walk this earth, but no one will disagree with them because even if the swill aint the hardest guy around him and his mates will outnumber anyone who disagrees with him about 15 to 1 and kick their head in, leving them for dead after kicking the unconcious body around the road.
