You have NO idea how this comment made me gaffaw, David! !!!!
I know you didn't mean it this way, but....over here, "cracker" is a word used by other races to racially insult someone of the Caucasian race. LOL
Humm interesting book to have. I think I may just invest in one myself!
Actually, I am quite aware of many sayings from your side of the pond. I've been a member of a forum (which sadly isn't as active now as it was once in the past, although it is still around) since 2007, and have made many friends from the UK. We have all been quite tickled at times to the many differences to the same words.... I love for instance, that you guys call a car's roof and trunk, 'bonnet' and 'boot'! Oh I just LOVE that! LOVE it!
I've never heard "cracker" explained however. But reading your reaction was the real intent on my end. You just crack me up so much sometimes David; a very interesting man as well!
