1) The hidden kiss is a metaphor from Peter
Pan. In short, it may represent preserved innocence- the part of oneself that remains forever youthful. Mrs. Darling in Peter
Pan, keeps her hidden kiss to herself; not even sharing it with Mr. Darling. One's hidden kiss, reveals the
truth of his or her innermost self; his or her true cares and beliefs; what makes a person tick.
2) In Peter
Pan, the hidden kiss is located in the corner of the mouth, where the lip begins to turn out. It could just be a term for that area of the mouth. Or, maybe Mrs. Darling's "hidden kiss" is there, because that is the area where her
facial expression changes… ruining her façade.
-If anyone is especially interested in this term, check out literary discussions that compare the metaphors of Mrs. Darlings hidden kiss, with Peter
Pan and Wendy. Very poetical
stuff!
