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.
