Unbalanced, indeed -- so crazy (3-5)
I believe the answer is:
one-sided
'unbalanced' is the definition.
(I've seen this before)
'indeed so crazy' is the wordplay.
'crazy' indicates an anagram.
'indeed'+'so'='indeedso'
'indeedso' is an anagram of 'ONE-SIDED'.
(Other definitions for one-sided that I've seen before include "Grossly unequal; biased" , "Biased, favouring one part over another" , "Indeed so (anag.)" , "Unequal like contest between badly matched opponents" , "Unfair or uneven" .)
