Definitions by TW_Lurker
Leng
Basically an evolved form of 'peng', but you don't feel as much of a prat using it. A positive description of something basically meaning 'well nice'. Can be used to describe people, but is much more appropriate when describing nice scenery, food & drink, or the day's weather. Very commonly used in Middlesex/SW London circa 2013.
Jills
Moderately offensive term with similar meaning to 'div' 'prat' or 'idiot'. Was an 80's London term that has been brought back to the streets of the South East thanks to the film 'The Firm' and online show 'The Lazy Generation'. It's delivery is best when it isn't over-used and is saved for when someone does something really stupid/clumsy/dumb. Can be extended to 'jillian' or 'jillcrest'.
