What X may represent (4)

Ross

I believe the answer is:

kiss

'what x may represent' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for kiss that I've seen before include "lightness of touch?" , "Smooch" , "Gentle touch of the lips" , "Embrace" , "Eg, smacker, peck" .)
