I believe the answer is:
scandal
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">a shocking thing</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 scandal that I've seen before include "content of 3 [RED TOPS]?" , "Subject of Sheridan's school" , "Something shameful or disgraceful, often public" , "outrageous behaviour" , "It injures reputation" .)
