That was the stereotype in the west too, it only reversed when having a tan meant you were wealthy enough to have been on a summer holiday somewhere sunny!
We said less unpleasant, comrade!
That is kind of accurate though if you're basing the story on history. Like if it's Robin Hood or King Arthur then the nobles will sound posh and the peasants won't.
Less of an excuse for it in high fantasy; I guess it's a quick way to telegraph to the audience who's who, but you're definitely right that it reinforces traditional class stereotypes.
Isn't this just a necessity of the storytelling medium? If the audience is English-speaking then they will appreciate a pun in English a lot more than a sign saying "this is an excellent pun in my made-up language, you wouldn't get it though". Even Tolkien basically says "this whole story has been translated into English"!
I don't think I've ever heard anyone say it IRL. It's a pretty minor thing really, use whatever insults you fancy, but if you want something very British you've got classics like muppet, nonce, pillock, bawbag.
Teakettle? Isn't that just a kettle?
Does your wee one watch a lot of American-voiced videos on YouTube or similar?
Any nation who makes cheesy chips and gravy their national dish is a friend and ally in my book
"cockwomble" just sounds like you're trying too hard, like a yank LARPing as a brit they read about on the internet
