I believe the answer is:
loiter
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">hang about</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for loiter that I've seen before include "Hang around, perhaps with intent" , "Hang around furtively" , "Linger - lurk" , "Dawdle, hang around" , "Linger, with intent perhaps" .)
