<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">quite a hit</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 swat that I've seen before include "Hit and crush (a fly)" , "land crushing blow" , "Hit a wasp or fly" , "Swift, sharp blow" , "Hit (flies, etc)" .)
