Ingratiating (6)

I believe the answer is:

smarmy

'ingratiating' is the definition.
(I've seen this before)

This is all the clue.

(Other definitions for smarmy that I've seen before include "Obsequious" , "Smooth" , "Bootlicking" , "Unpleasantly suave or ingratiating" , "Unctuous" .)

I've seen this clue in The Telegraph, The Guardian, The Times, the Wall Street Journal and the Newsday.com.
