==Slang== 
 Adding slang terms related to Guinness is going to be problematic. One editor has contacted me over this issue with the rather unusual qualifier that he is a resident of Dublin, Ireland, whilst I am not. It's not obvious why this is relevant, unless there is a case for saying Dublin slang for Guinness is more noteworthy than, say, Barnsley slang for Guinness. Anyway, I digress... such material should not be included in any article unless it can satisfy core Wikipedia policies such as WP:V and WP:N. In order to do this, reliable sources will be needed; if the terms are indeed noteworthy, I'm sure there'll be coverage in newspapers, books or magazines. If not, they are basically trivial cruft and/or neologisms that really have no place on Wikipedia (see WP:NOT). But if sources emerge, feel free to reinstate!
