Ingratiating, falsely charming (6)

I believe the answer is:

smarmy

(Other definitions for smarmy that I've seen before include "Obsequious" , "Oily" , "Excessively flattering (R, not L)" , "Unpleasantly suave or ingratiating" , "Excessively ingratiating" .)

I've seen this clue in the Sydney Morning Herald.
