Does nothing but slide around (5)
I believe the answer is:
idles
'does nothing' is the definition.
(I've seen this in another clue)
'slide around' is the wordplay.
'around' indicates anagramming the letters.
'slide' with letters rearranged gives 'IDLES'.
'but' is the link.
(Other definitions for idles that I've seen before include "Spends time doing nothing" , "Wastes time" , "Lazes around" , "Avoids working" , "Lazes about, just ticks over" .)
