<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">gushing review</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 rave that I've seen before include "Enthuse; rant" , "Enthusiastically favourable review" , "Talk wildly and angrily" , "Fume" , "Wild party; go mad" .)
