Now, a janner, as will be correctly stated by one who was born and lives here, is a term used by most outsiders to describe the people who live in Plymouth, Devon.
Not to be mistaken for a swilly which is actually a sub-species here and should be wiped out very quickly. For further infomation on these rodents see chav.
Normal Janner: Fuck off.....(runs away)
"He's a loud-mouthed Janner bastard".
The word is rumoured to derive from the fact that many locals are called John, but when asked their name will say "Moi namez Jaaan"
Whilst Janner is a blanket term to refer to anybody with strong local origins, a farmer can also be called a "Bez"
There is a simple test to see whether or not someone is a Janner - ask the the name of a small castle town on the Devon / Cornwall border. A non Janner will say "Launceston", while the true Janner will reply "Laanson".
"An old Janner just drove past in his muckspreader, and now I'm covered in cow shit"
