Why do Americans have such cheesy accents?

I have a standard English accent

You know there are many different American accents right?

They don't have a "cheesy accent", I don't think an accent can be "cheesy"- you associate Americans with cheesy behaviour from what you see on TV and film and therefore associate their accents with "cheesiness".

I also ask for the bathroom when I need the toilet because it's more polite than saying "where's the toilet"

Everyone has an accent.

Yeah, the first part of what you wrote may be true. Lots of American movies are broadcast on British TV, good ones, but maybe there is a lot of stereotyping in them so I have associated the accent with cheesiness. But, to me, exaggerating vowels in any accent - British or American - is cheesy and patronising. Most, if not all American accents have exaggerated vowel sounds.

Agree to disagree with you on the second one. Saying 'bathroom' may confuse the person you are talking to, which makes the situation awkward. I think it is more honest and down-to-earth to ask where the 'toilet' is, if you need to use the toilet, and it makes sense, because there is no bath in public toilets. I just don't think people should be ashamed about having a poo or wee, when it is a natural bodily function.

I live on the South coast of England, I have neither a posh accent nor a chavvy accent. I have a standard English accent. I used to like the American accent, but now it does my head in a bit. I'm talking to an American guy on Snapchat and instead of messaging me, he talks to me to me through videos. I think he is from Minnesota. It always sounds like Americans are trying to advertise a product. It sounds really patronising and informal to me. The six main reasons I can't stand it is because:

1) They exaggerate 'o' sounds which ought to be short. E.g. instead of saying 'God' which should take less than 3/4 of a second, they say 'Gaaahhhd' which takes at least 3/4 of a second to a whole second. This is cheesy and unnecessary.

2)Instead of saying bath using the 'a' sound which is in the word 'card' they use the 'a' sound in the word 'cat'. I can't stand Northern British accents for this reason, and I would love to watch Coronation Street and Emmerdale, the storylines are decent apart from the crap acting in these soaps, but the accents drive me insane.

3) They ask to go to the 'bathroom' or 'restroom' in order to use the toilet, thus taking the word 'bath' out of context. If you need a 'bath' than ask where the 'bathroom' is, if you need a poo or a wee then ask where the 'toilet' is, if you need a rest then go lie down in your 'bedroom' at home. There is no bath inside public toilets and there's no need to be ashamed about a natural bodily function. I know this is a critique of cultural customs, rather than the accent itself, but the accent annoys me by mere association of this cultural custom, because it doesn't make sense.

4) They fail to pronounce the 't' sound properly. E.g. When they say 'butter' it sounds like they are saying 'budder', with very soft 'd' pronunciation. There is a difference between 't' and 'd', which is why they are two separate letters in the 26-letter alphabet.

5) They sound like they are trying to advertise/convince you of what they are saying.

6) The American accent sounds informal because the 't's aren't pronounced properly, but yet serious at the same time because this accent exaggerates vowels ('Daaahhhwg' rather than 'dog' which makes it appear as though American people are trying to be serious, or acting like what they are saying is important whilst also acting casual by not pronouncing the 't's properly. The accent contradicts itself.

The accents which have less exaggeration and don't sound as informal aren't bad though. The New York one is one of the least annoying ones.

Maybe I don't mind softer American accents, because I too have a sotfer English accent (in that mine is neither posh nor chavvy)?
