Idiom meaning "Why are you in a bad mood?", implying discontent with the other person's attitude. As it is a rhetorical question, no response is expected. Often used in situations where the person being asked is angry as the result of an underlying cause and therefore snaps at people who have nothing to do with this cause.
A rube. Someone naive, happy and care free. Not necessarily stupid but are trusting too a fault and always think the best of ppl. Cornslap’s are very nice and polite. Often people think they are gullible and easily tricked but that is not the case. They have a streetwise ‘barnyard’ sensibility. Midwesterners in pop culture are often portrayed this way.
Radar on MASH and Rose on the Golden Girls are perfect examples of a cornslap.

To declare your preference for "soft" or "soggy" cornflakes is to express a desire to branch out as a musician and explore the possibilities of artistic maturation. To steadfastly swear allegiance to crispy cornflakes is to commit to stabbing your musical rival in the head and committing arson.
The topic of cornflakes can also be usefully employed to deter metal guys from boring you with their inane banter.
