After the Civil War,some whites were so poor they had to crack their own corn because the could not afford mill.

British slang, meaning a thing that is excellent.

Cracker, is a term of contempt for the "poor" or "mean whites," particularly of Georgia and Florida. The term dates back to the American Revolution, and is derived from the "cracked corn" which formed their staple food.

A chemical herb which induces the powers of bliss, essentially getting one high.

Cracker is a game played between 2 or more people with dicks. A cracker is placed before each crank and on the count of 3 the participants race to ejaculate on their cracker. The last one to complete the orgasmic release must eat everyone else's spooge covered saltine.

Not to be confused with the lower-case-initialled word, Cracker is a kick-ass police drama series from the UK starring Robbie Coltrane (Hagrid in the Potter movies) as a criminal psychologist in the employ of Her Majesty's Police. He is Scottish (of course) and grimly determined to have show-down after show-down with his wife over his additions to gambling, cigarettes and alcohol. Has a bit on the side with Sergeant Jane Penhaligon (whom he refers to as "Panhandle"), played by Geraldine Somerville (Lily Potter in the movies). He is deeply pessimistic and cynical and possessed of an ineluctable Celtic perception (sans tinsel and cliched stuff; think of the real Scotland) of the fundamental bleakness of the human condition. Sarcastic as hell. Unforgettable.
Oh, yes, the criminal cases are kind of interesting, too.
