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.

Plymouthian slang word originally used to describe people originating from the part of plymouth called swilly. This word is now being used to describe anyone who fits into the sterotype chav or kevdue to the fact that most "swills" are what people believe to be chavs or kevs.The majoraty of "swills" congragate in huge circles on street corners smoking,drinking, and/or doing very soft drugs, while glaring at passers by and threatening to slit thier throat. Although intimadating in groups the "swill" is no more than a very weak thug with an extremely poor upbringing and it is often the case that the swill has witnessed violence towards his parents and seen his relatives take drugs before him.There is also a very easy way to tell if you are dealing with an ordinary chav/kev or a swill as the swills tend to use the letter "o" in places where the leteer "u" should be E.G: "Fock" instead of "Fuck" and "Cont" instead of "Cunt"
A swill just threatend to kill me iff i ever go to the shop again.
