<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">rub it in</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for gloat that I've seen before include "Show malicious smugness" , "Look triumphant" , "Smugly look on another's misfortune" , "Exult maliciously" , "Look like the cat who got the cream" .)
