Smarmy, unctuous (7)
I believe the answer is:
fulsome
This clue is a double definition.
'smarmy' is the first definition.
(I know that smarmy can be written as fulsome)
'unctuous' is the second definition.
(I know that unctuous can be written as fulsome)
(Other definitions for fulsome that I've seen before include "Excessive (praise)" , "Adulatory" , "Excessively fawning" , "Generous, abundant" , "Insincerely gushing (e.g. tribute)" .)
