[Dianne]

In British English slang, particularly of north-west England this means lucky or more accurately flukey. It is usually applied to someone else who has just had a particular piece of outrageous or undeserved luck.
It is typically used with this meaning by young men and schoolboys throughout the north-west of England, not just Liverpool and Merseyside, but also Cheshire, etc. However, the usage can occur in other regions of England as well. It has been used to have this meaning throughout most of the period since at least the end of World War Two.
