Lots of bucks (4)
I believe the answer is:
deer
'lots of bucks' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for deer that I've seen before include "Bucks and does?" , "Eg, stag or doe" , "Red, roe or fallow" , "Source of venison" , "Wild animal" .)
