Cha·grin n.  Vexation; mortification.
     I must own that I felt rather vexation and chagrin than hope and satisfaction.   --Richard Porson.
     Hear me, and touch Belinda with chagrin.   --Pope.
  Syn: -- Vexation; mortification; peevishness; fretfulness; disgust; disquiet.
  Usage: Chagrin, Vexation, Mortification. These words agree in the general sense of pain produced by untoward circumstances. Vexation is a feeling of disquietude or irritating uneasiness from numerous causes, such as losses, disappointments, etc. Mortification is a stronger word, and denotes that keen sense of pain which results from wounded pride or humiliating occurrences. Chagrin is literally the cutting pain produced by the friction of Shagreen leather; in its figurative sense, it varies in meaning, denoting in its lower degrees simply a state of vexation, and its higher degrees the keenest sense of mortification.
  “Vexation arises chiefly from our wishes and views being crossed: mortification, from our self-importance being hurt; chagrin, from a mixture of the two.”   --Crabb.
