a mildly derogatory slang used to refer to Bangladeshi-Britons, especially those Bangladeshi-Britons of Sylheti descent. They speak Bengali horribly with
thick Sylheti accents and those born and brought up in the U.K. usually speak English as well with a very
thick accent. Their English dialect depends on the region of U.K. they are brought up in. All Londoni families own a restaurant which serve Indian cuisine and is a hub for providing jobs to their newly-arrived relatives from Sylhet who have decided to stay back illegaly.
These
people try to give an impression of being really
rich and well off to their Bangladeshi
friends and relatives and think they are really of a higher class with more status and cooler than them just because they live in England, when in reality they are a bunch of jokes who neither the British nor the Bangladeshis really give a shit about. They have horrible sense of style and have no clue what big idiots other
people think they are.
Note: This in no way applies to Bangladeshis living in other countries
like the United States or
Canada where the Bangladeshis living are actually sophisticated and educated unlike their British counterparts.
