Humour eluding nuts (7)
I believe the answer is:
indulge
'humour' is the definition.
(I've seen this before)
'eluding nuts' is the wordplay.
'nuts' is an anagram indicator (nuts can mean crazy).
'eluding' with letters rearranged gives 'INDULGE'.
(Other definitions for indulge that I've seen before include "Partake" , "Coddle while eluding." , "Humour; spoil" , "take to the drink?" , "Treat with (undue) favour" .)
