Any accent that pronounces words the way the dictionary says they should be pronounced
Personally I think the RP accent is old-fashioned and pretentious. Just because someone decides this is the way a word should be pronounced, doesn't mean its correct. Its just deemed the standard pronunciation by a handful of people.
Also, the standard accent changes over time. The midland accent used to be considered the standard, but now Southern English is.
RP isn't the 'correct' accent, it's just the standard. There are many variations, but that's not to say they are incorrect. Just different varieties of English.
People who say 'totesamazeballs' definitely aren't on my playlist for friends. It makes no sense, and is as bad as saying 'hashtag' before a word/phrase.
I feel an unbelievable urge to maim the users of "reem", "yar" (inability to just say "Yes"), "init". I also hate certain individuals' need to have the last word, even when they just start muttering "Oh really?" and "Is that right?" or "I don't think so.". Very annoying.
