"I've seen better" (3)
I believe the answer is:
meh
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">i've seen better</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 meh that I've seen before include "Who cares" , "expression of indifference" , "Unexciting (modern slang)" , "Not much cop" , "am I bovvered?" .)
