Lemon or turkey
I believe the answer is:
I believe this clue is a double definition.
'lemon' is the first definition.
(both can mean a poor example of something)
'turkey' is the second definition.
(I know that turkey can be written as dud)
(Other definitions for dud that I've seen before include "Just a palindromic flop" , "Valueless" , "Useless, ineffective" , "'Flop, turkey (3)'" , "Failed, worthless thing" .)
