<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">don't forget about me</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 ahem that I've seen before include "Throat clearing sound to catch attention" , "Attention-grabbing expression" , "Polite noise to draw attention" , "Attention-getter" , "Exclamation attracting attention" .)
