<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">defeated contestant</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for loser that I've seen before include "One who is habitually unsuccessful" , "one that's been left behind" , "lemon" , "Unsuccessful competitor" , "one plays without success" .)
