So - stereotypical Brits:-

Brass band playing. (At least they weren't playing The Beatles.)
Street party in the background. (We all love a kneesup.)
Cup of tea on the table - of course we never drink coffee.
Furniture - typically British - actually what's missing is curtains. (Most houses have curtains at the window.)

Onto yellow:-

Bowler hat, briefcase, furled umbrella and tie - banker! (Actually only the Orange men in marches in NI would wear this get up: They are scarily British.)
Flat cap, monocle, tweed jacket, plus fours - upper crust.
Punk fashion - working class.
Morris Dancer - maybe the least stereotypical outfit here.  We do still have Morris dancers, and they are all men.
Wearing the Union Jack all the time - no (I do have one in SL, but I never wear it in RL.)
Red, white and blue - Hooray for the union jack and the disunited kingdom.
The accents - RP or Calling everyone "geezer" in a cockney accent - we have so many accents and dialects, it would scare you.

 

M&M's are colourful button-shaped sweets, produced by Mars, Incorporated. The multi-coloured sugar coating, has the letter "m" printed in lower case on one side.  There are a variety of fillings, usually milk chocolate, or peanuts.  M&M's originated in the United States in 1941, and are now sold in as many as 100 countries.

So, if you want to be "typically British" eat Smarties.
