Girl men recollected as source of bad luck (7)
I believe the answer is:
gremlin
'source of bad luck' is the definition.
(gremlins can be sources of bad luck)
'girl men recollected' is the wordplay.
'recollected' is an anagram indicator (letters recollected and rearranged).
'girl'+'men'='girlmen'
'girlmen' with letters rearranged gives 'GREMLIN'.
'as' is the link.
(Other definitions for gremlin that I've seen before include "In the works, it upsets things" , "Impish troublemaker" , "Aerial imp" , "Cause of mechanical failure?" , "Unexplained technical problem or fault" .)
