Alistair Leslie Graham, better known as Ali G, is a satirical fictional character created and performed by English comedian Sacha Baron Cohen.

A faux-streetwise poseur from Staines, England, Ali G speaks in rude boy-style Multicultural London English.

Baron Cohen has stated that BBC Radio 1 DJ Tim Westwood was an influence on the development of his character.

[8] Ali G, a faux-streetwise poseur with a deeply stereotypical view of the world, first came to prominence on Channel 4's The 11 O'Clock Show as the "voice of da yoof" in 1998.

He and his then-wife, actress Isla Fisher, locked themselves in the bathroom for 40 minutes to secretly put on his costume, after telling people he had food poisoning.

In the same comic vein, he also makes reference to stockbroker belt towns in the area, such as Egham, Langley and Englefield Green with which he contrasts Staines.

Ali G speaks a comical patois in keeping with his delusions of being black with Jamaican ancestry and peppered with such catchphrases as "aight" or "aiii" (alright), "booyakasha", "big up yaself", "wagwaan", "west side", "batty boy", "respek", "for real", "punani", "check it", "wicked" and "keep it real".

[20] The comedian Felix Dexter has said that he appreciated the humour of an innocent ignoramus confronting an expert with neither understanding the other, but felt that "a lot of the humour is laughing at black street culture and it is being celebrated because it allows the liberal middle classes to laugh at that culture in a safe context where they can retain their sense of political correctness".

[21] Fellow comedian Victoria Wood criticised Baron Cohen's style of comedy, saying that his "endless setting up of victims" was "tiresome" and akin to "laughing at lunatics".
