The US Food Network, a TV channel, has published a glossary of celebrity chef Jamie Oliver's slang (here) so that American viewers can understand him. They are also considering subtitling his programmes. The glossary includes whack it and chuck it (both mean 'put it'), pukka (excellent), over the moon (happy), hen party (bachelorette party in US) and lovely jubbly (really nice).
I mentioned Jamie Oliver's accent and dialect in this post. Jamie Oliver speaks 'mockney' (sometimes written Mockney with a capital M), which is an affected (ie mock) Cockney, or London, accent. Oliver had a middle-class upbringing in the Home Counties but affects a working class London accent to endear himself to TV viewers.
