What is Clue Hug?
1.
A hug given to a detective as a reward for finding a clue. Typically an awkward gesture, usually given by a psychotic fan. Clue hugs are not to be given when the detective is summing up the crime.
(After finding a clue, Marci approaches Monk with her arms open.)
Monk: What are you doing?
Marci: Clue hug!
