Performed at do with cute eccentric (5,3)
I believe the answer is:
acted out
'performed' is the definition.
'at do with cute eccentric' is the wordplay.
'with' is a charade indicator (letters next to each other).
'eccentric' is an anagram indicator.
'at'+'do'+'cute'='atdocute'
'atdocute' is an anagram of 'ACTED OUT'.
(Other definitions for acted out that I've seen before include "Gesturally expressed" , "performed as if on stage?" .)
