I love British accents a ton, they're so enticing and sexy. I also like Australian, Scottish, Japanese, Irish, Italian, New York (specifically Staten Island accent) , Boston , Dutch, Swedish and Canadian.
I guess I have an accent, I'm sure we all do have some accent, I just don't noticed. Considering I'm from St.Louis I guessing a St Louis accent accent? I know some St.Louisians and Missourian say "warsh" instead of "wash" and "farty-far" (yes I know it sounds like fart.) instead of "forty-four" and I can find myself saying some of those words like that sometimes.
@Somniac: That is just like the best accent ever. I mean EVER.
But, in any case, I like English and Irish and Scottish accents and (Welsh and) the like. Although that's not to say there's an accent I don't like; I think it's all interesting.
I kinda get annoyed when people say they don't have an accent. I mean, to ourselves that's true, but to other people it won't always be. That being said, I do have the Midwestern you-don't-have-an-accent accent, the one people usually look to TV newscasters or general American characters for. Although there are probably elements of others in there; I often dismember hard consonants like "t" and "g" from a word, like the strange "ne'ermine" instead of the actual word "nevermind." Words like "tantalizing" become "tannalizing," and "I can't even" becomes "I canneven."
100% of English dialects, Irish, Polish, 90% of American dialects, pretty much anything European where they try to speak English and it comes out all broken. Except French, not really a huge fan of French accents when spoken in English.
