Do lie about being greased (5)
I believe the answer is:
oiled
'being greased' is the definition.
(I've seen this before)
'do lie about' is the wordplay.
'about' indicates anagramming the letters.
'do'+'lie'='dolie'
'dolie' with letters rearranged gives 'OILED'.
(Other definitions for oiled that I've seen before include "wasted" , "Oldie (anag)" , "Anointed" , "get drunk" , "running smoothly?" .)
