Kiss, so to speak (6)
I believe the answer is:
smooch
'kiss so to speak' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for smooch that I've seen before include "Kiss and cuddle (colloq.)" , "neck" , "Snuggle" , "Kiss and caress slangily" , "Canoodle" .)
