One slice upon the other. John and his maid were caught lying bread and butter fashion.—To quarrel with one’s bread and butter; to act contrary to one’s interest. To know on which side one’s bread is buttered; to know one’s interest, or what is best for one. It is no bread and butter of mine; I have no business with it; or rather, I won’t intermeddle, because I shall get nothing by it.
