I'm not sure where to put this, and I'm coming at it from a light hearted direction, but what is it with the "word" that is the three letters u,g,h that I see so much in posts not just here but elsewhere? Maybe because I am quite old and I was brought up in a country that more or less follows British English patterns, I am used to using, in informal spoken and written stuff like chatting to people, notes and web forum posts, etc, "ugh" to mean something like "yuk" or (the abominable!) "ewww". For example when discovering a mouldy thing in the fridge or doggy-do on a shoe. I pronounce it (roughly) "ure" (without any rhotic 'r'). Or "eure". But these days a lot of (younger?) people use it to mean they are dissatisfied or ticked off or tired of something... am I right?
