I believe the answer is:
unpopular
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">not liked</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for unpopular that I've seen before include "having few friends" , "Lacking appeal" , "Not well-liked" , "Generally disliked by people" , "not favoured" .)
