Spurned, I fail badly; did I mean to say that? (8,4)
I believe the answer is:
freudian slip
'did i mean to say that?' is the definition.
I can't judge whether this defines the answer.
'spurned i fail badly' is the wordplay.
'badly' indicates an anagram (letters in the wrong order).
'spurned'+'i'+'fail'='spurnedifail'
'spurnedifail' is an anagram of 'FREUDIAN SLIP'.
Can you help me to learn more?
(Other definitions for freudian slip that I've seen before include "Mistake revealing hidden concerns" , "Unintentional error" , "Error betraying inner thoughts" , "Words revealing unconscious thoughts" , "Slip of the tongue, revealing unconscious thought" .)
