Fighting for nominated club, suffering exposure by mistake (8,11)
I believe the answer is:
wardrobe malfunction
'fighting for nominated club suffering exposure by mistake' is the definition.
I can't judge whether this definition defines the answer.
'fighting for nominated club suffering' is the wordplay.
'fighting' becomes 'war'.
'suffering' is an anagram indicator.
'for'+'nominated'+'club'='fornominatedclub'
'fornominatedclub' with letters rearranged gives 'drobemalfunction'.
'war'+'drobemalfunction'='WARDROBE MALFUNCTION'
Can you help me to learn more?
(Another definition for wardrobe malfunction that I've seen is " It reveals".)
