The British culture is a very defined very old culture. The main point to British culture is that they hate everybody and beyond all reasonable doubt they hate the Americans more than anyone else bar the French. The British utterly hate the Americans and mabey 1% of the population might actually like America.
Religion is not very big in Britain and mabey about 10% of the population are actually religious or actually belive in some sort of god.
Britain is well known for drinking heavily at young ages, having sex from about the age of 12-16 and kicking the crap out of each other pretty much daily. Fighting is a greatly loved sport in the country and 75% of the population love to participate.
Things you should not do in Britain. If you have an American accent do not talk. This will likely get you into a fight. No not use the peace sign due to it being remarked as higly offensive.
Also absolutly never say soccer. This will most likley get your murdered, shot, tortured and many other imaginable things.
Football is the greatest loved sport in Britain with Cricket, Rugby, Gold and mabey Tennis.
Most people in Britain grow up with an ambition to claim bennifits, become a hair dresser or a car mechanic.
