What is the difference between a creek and a crick? Please add where you are from in your answer. One is a body of flowing fresh water smaller than a river, and the other is a pain in the neck. Unless you're from Appalachia, in which case the latter (crick) is an alternative pronunciation of the former (creek). I have yet to find corroborating evidence of this sense/connotation of the word.
