"Don't worry about it" (2,5)
I believe the answer is:
no sweat
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">don't worry about it</span>' is the definition.<br/ ><span class="explanation-format__explanation">(phrase meaning there's nothing to worry about)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for no sweat that I've seen before include "Not a problem! (informal)" , "That's a piece of cake (anti-perspirant unnecessary!)" , "Not a problem (US colloq.)" , "There shouldn't be any objection" , "That's not a problem!" .)
