<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">starbucks size</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for tall that I've seen before include "Towering" , "Remarkable" , "Bigger than average" , "Lofty; unlikely" , "hard to believe in" .)
