Thrill Friday's child (7)
I believe the answer is:
frisson
'thrill' is the definition.
(I know that thrill can be written as frisson)
'friday's child' is the wordplay.
'friday's' becomes 'Fri's' ('Fri' can be a synonym of 'friday').
'child' becomes 'son' (male child).
'fris'+'son'='FRISSON'
(Other definitions for frisson that I've seen before include "Kick" , "Shiver of excitement" , "Shudder of excitement" , "Strong feeling of excitement, thrill" , "Emotional thrill" .)
