Something sticky kisser served up (3)

Ross

I believe the answer is:

gum

'something sticky' is the definition.

'kisser served up' is the wordplay.
'kisser' becomes 'mug' ('mug' can be a synonym of 'kisser').
'served up' says the letters should be written backwards.
'mug' reversed gives 'GUM'.

(Other definitions for gum that I've seen before include "Leaving body" , "Gingeva is its technical name" , "To stick with adhesive" , "Eg, a eucalyptus" , "Chewy stuff, hard to clean away" .)

I've seen this clue in The Times.
