I agree that a lot of discussions like this is about fashion. There are a few old fashioned (but not traditional) usages that I find cringeworthy, such as 'why oh why'? 'Simples', 'peeps' and 'rant over' (sorry OP ? ). Words or phrases catch on for a while, usually because of popular culture, but then drop out as quickly as they came in, and when people cling to the dropped out ones it sounds like nails on a blackboard.
I've just remembered another one like that - 'No way, José', and I know I've said it before, but I will never get used to 'Uni'.
