Whip; sell (4)
I believe the answer is:
flog
I believe this is a double definition.
'whip' is the first definition.
(synonyms)
'sell' is the second definition.
(I've seen this before)
(Other definitions for flog that I've seen before include "Beat with whip or slangily sell" , "Lash" , "Exchange for money" , "Thrash" , "Beat with a whip or rod" .)
