A rich tapestry of dialect.
I like the Yorkshire "Now then!" which can be a greeting or a scolding and a lot between.
There used to be a trend round here for things being Pure....
Pure boging - Not very nice
Pure brilliant - Good
Pure dead brilliant - Very Good
Pure Raging - Not very happy
Fifers like to add "Like" to the end of sentences. "He was pissed like...."
One that caught me out was a colleague from Edinburgh you used to add "Aye" to the end of sentences, but he used it both as an affirmation and as a question (for you to agree), so would sometimes just stare at whoever he was talking to waiting on an answer. Bizarre.
Henry Cole adding "Man" to his sentences is rather annoying. Which reminds me, someone gave me his book to read.
