I believe the answer is:
idle
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">just sitting around</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 idle that I've seen before include "Dormant" , "'Lazy, not doing anything (4)'" , "Unoccupied or not in use" , "not being engaged" , "Run out of gear" .)
