A very brief history
According to Wiki history, The 18th-century English were the first to use the term “cracker”, applying it to (yes, you guessed it) Scotts, Irish and even fellow English who, unlike most English settlers in America, showed their rather “inferior” (understand un-English-like) judgment in that they loved the remote southern backside of America.
Sir William Robertson: “Who’s ever heard of such un-English like oddity? What a backward lot! English Hillbillies playing hide and seek and God knows what other child’s games with geese, roosters and frolicking hideous dance steps under the lead of musical donkeys…”
Real circus in the early 1900s
The “cracker” was simply someone who lacked everything that made the English bulldog spirit and its fortitude of character.
“I should explain to your Lordship what is meant by Crackers; a name they have got from being great boasters; they are a lawless set of rascals on the frontiers of Virginia, Maryland, the Carolinas, and Georgia, who often change their places of abode.” letter to the Earl of Dartmouth http://en.wikipedia.org/wiki/Georgia_cracker
Africans share their thoughts on the subject
Abu Bakar: “So I know this has nothing to do with us, Africans. But imagine this. One day in 1925 in North highs Hoals, Georgia, I am sitting at the bar, and two white people are sitting next to me: one on my left, the other on my right. One of them passes me a beer and says:
“Hello Governor! Pass this on to the genuine article cra*ker sitting next to you. Tell him I say:
Cheerio noble cra*ker! Let’s drink to Georgia’s inroads and California way out by the sea,
Where a woman’s ass,
And a whiskey glass,
Made a horse’s ass of my noble wee wee!
So I pass the beer, I open my mouth and say …
“Here is my noble wee wee…for you, sir!”
This is how you diffuse a conflict, son!
