Hey, if you value making that corner more than the life of your passenger, then I feel fully justified in valuing my car more than them too. Yes, we would probably say smash more than crash. It's only something I realise when I think about it, though, not any sort of real upsidedownspeak. A proper Aussie synonym is bingle, which we named after an airhead celebrity who is famous for saying "Where the bloody hell are you?" in a tourism ad for Australia. It was generally regarded as trying a bit hard and Bingle is a typical thot type.
