I have a chapatti on my shoulder and not a chip thank you.[COLOR="Silver"]
I think we have a cross cultural language problem here. so at the risk of seeming paternalistic,
The term quoted above has nothing to do with fast food it originates in a trade, Joinery and cabinet making where shaping would first be done by "chipping out" with rough tools before using finer tools and then sanding to a smooth finish and finally polishing.
Word Origin and History for snitch Expand. n. "informer," 1785, probably from underworld slang meaning "the nose" (1700), which apparently developed from an earlier meaning "fillip on the nose" (1670s).
During these turbulent times in English History informing on someones political or religious affiliations and activities could earn handsome rewards or perhaps save a person own head from the noose and Other more dreadful ends. Since then the term Snitch has referred to someone poking their nose in where it is resented as in the example I gave before.
I hope this clarifies things and puts an end to any if not all animosity between us.
