Flash poseur dancing around her, for example (9)
I believe the answer is:
superhero
'her for example' is the definition.
I can't judge whether this definition defines the answer.
'flash poseur dancing around' is the wordplay.
'flash' becomes 'her' (I can't explain this - if you can you should believe this answer much more).
'dancing' is an anagram indicator.
'around' indicates putting letters inside.
'poseur' is an anagram of 'supero'.
'her' placed within 'supero' is 'SUPERHERO'.
(Other definitions for superhero that I've seen before include "Fictional character with special powers" , "Batman, say?" , "comic book creation" , "Spiderman, for example" , "people didn't notice in Kent, for one" .)
