- verb to vomit. This term, in use among Australian surfies and others in the 1960s, was imported into Britain later in the decade by the strip cartoon The Adventures of Barry McKenzie. The writer, Barry Humphries, derives it from the warning cry ‘Watch under!’, perhaps used by sailors. An alternative derivation is from ‘Chunder Loo’ as rhyming slang for spew, from the name of a character used in advertisements for boot polish fifty years earlier. Already established in Britain, especially among young sportsmen and drinkers, there are signs that this and other Australianisms are making headway in the USA following the success of the Australian comedy film Crocodile Dundee in 1987.
