Flog junk husband collected (6)
I believe the answer is:
thrash
'flog' is the definition.
(thesaurus)
'junk husband collected' is the wordplay.
'junk' becomes 'trash' (I've seen this before).
'husband' becomes 'h'.
'collected' indicates putting letters inside.
'trash' placed around 'h' is 'THRASH'.
(Other definitions for thrash that I've seen before include "Noisy, lavish party" , "Beat; party (colloq.)" , "Whip repeatedly" , "Hit hard" , "tan" .)
