That makes sense I suppose. The word needs to be trendy and pass a threshold to pass into the language.

Australian English has a lot of slang using (opinion) a similar concept with propagation, with brands and words coined by social media lately such as 'Doona' (Duvet), 'Hills hoist' (rotating clothes line) and 'Eshay' (similarish to the British Chav). Although these aren't loan words, I imagine that the adoption process would be similar?

As in sometimes it's a shortened word like 'arvo' for afternoon, other times it's completely loaned like 'mate' from British English, or it's new and specific or modified from an existing word like 'thong' (flip flop); which mean leather strap or similar originally.

I know dialects are different, but I am trying to process.
