Smooch (4)
I believe the answer is:
kiss
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">smooch</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that smooch can be written as Kiss)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for kiss that I've seen before include "Neck - peck" , "Smack; peck" , "Peck (on cheek or lips?)" , "Salute" , "Expression of love" .)
