Shiver of excitement (7)
I believe the answer is:
frisson
'shiver of excitement' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for frisson that I've seen before include "Shudder of excitement" , "Strong feeling of excitement, thrill" , "Emotional thrill" , "Kick" , "A shudder or thrill" .)
