Most of the time people forget that Britain contains England, Scotland, Wales and Northern Ireland, all of which have their own regional accents as well.
English person: I am English if that is what you mean
American: I love your British accent!
English person: Are you retarded?
If one does admit the existence of a British 'accent', then there are literally dozens of variations, according to the variety of forms of enunciation present in the British Isles:
Queen's, I.e. accent-less.
And many others.
Cool American: Your british accent is soooo cool speak more
Me: Okay...what should i say
cool American: Anything!!!
iEnglish/i accent is just TOO gorgeous: maximises chances of a girl swooning at your first words.
Upper class accent "I'm at Oxford" accent is the best one.
With an English accent like that, even an idiot can sound like the smartest most gorgeous man alive.
"He's got an British accent!"
"Shit! I love him already!"
The south east accent is the one most frequently heard outside of Britain in the media and in films (curse you Hugh Grant!) so people don’t really hear many different accents from across the British isles which has led to the stereotyping of the "British accent".
Saying "British Accent" is just as stupid as saying "North American Accent", in as much as "Britain" is more a reference to the land mass that contains within it the countries England, Scotland and Wales, so also North America contains The U.S.A., Canada, Mexico etc.
We here in The U.K. like to be called by our country of habitat, namely, England, Scotland, Wales, or Northern Ireland. (Please never get the Northern Irish Mixed up with Irish or any other english speaking accent.. They hate that just as much as we hate to be called British.) All of this hangs nicely around our accent. According to the country we live in, we like to be known as having English, Scottish, or Welsh accents. Keep calling us British, or saying that we have a British accent, and we'll start calling you Americans "Canadian" or even "north American". And we might even say that you sound like the Canadians, we know you'd hate that, but the thing is, we can actually tell the difference.
(PS:Northern Ireland is not officially classed as being in Britain, though the British government does rule it, just as it used to rule many other countries around the world. Thats why it is often referred to as Great Britain and Northern Ireland. Together this is referred to the United Kingdom, something that is totally different from Britain.)
All who watch the film (outside the U.S.) think: Stupid American tosser, its just a thick Yank trying very hard to do a cockney accent, and failing miserably. Plonkers.
It is not specifically "English Accent". If you want to say someone has an English Accent. Then it is common sensical to say "English Accent" as opposed to the potentially irritating generalization.
Make no mistake. I, for one, and many others like me will not let you use the term "Britsh Accent" (OR British anything else where you actually should have said English)
without some form of protest. Be it verbal or physical.
