Excess fudge under candy (10)
I believe the answer is:
redundancy
'excess' is the definition.
(I know that redundancy is a type of embarrassment)
'fudge under candy' is the wordplay.
'fudge' is an anagram indicator.
'under'+'candy'='undercandy'
'undercandy' anagrammed gives 'REDUNDANCY'.
(Other definitions for redundancy that I've seen before include "Loss of job" , "Surplus, especially in one's job!" , "Dismissal" .)
