London slang. A
derogatory term for a certain type of person from Australia, New Zealand or South Africa who now lives in the UK. More often used to describe women but can be applied to men. Can also be used to describe the places
frequented by Kirbys.
Kirbies are very fond of alcohol and/or drugs and all the
associated behavior. The women are usually blond (or died blond), horribly slutty and have an unpleasant bitchy attitude. The men are usually large rugby playing types (or wanabees) often with blonde hair, very predatory towards women and sometimes quite aggressive.
This word originates form a short lived UK TV show called The Last Chancers which featured a character called Kirby who was as described above.
Note on usage: This word could be considered very offensive as it shows a complete ignorance of the difference between three very different counties.
