What's more following boob job? (6)
I believe the answer is:
errand
'job?' is the definition.
(thesaurus)
'what's more following boob' is the wordplay.
'what's more' becomes 'and' (I've seen this in another clue).
'following' is a charade indicator (letters next to each other).
'boob' becomes 'err' (both can mean to make an error).
'and' put after 'err' is 'ERRAND'.
(Other definitions for errand that I've seen before include "Gone up" , "Short assignment" , "Useful journey" , "Short mission -- ran red (anag)" , "An ...... of mercy is a journey to relieve distress" .)
