... tho it is my impression that 'jerk' has emerged more into mainstream than 'tosser'. Until recently, 'tosser' would not have been usable in society [probably still isn't, in fact]; whereas "what a jerk!" seems to me the sort of thing one might even have heard in 1930-40s movies — something William Bendix might have said in one of the McGehrins·From·Brooklyn films, e.g: presumably the Hays Office being too ingenuous & innocent to recognise its true origin?
