Lied about being lazy (4)
I believe the answer is:
idle
'lazy' is the definition.
(similar in meaning)
'lied about' is the wordplay.
'about' indicates an anagram.
'lied' with letters rearranged gives 'IDLE'.
'being' is the link.
(Other definitions for idle that I've seen before include "Fruitless" , "Still" , "having no effect" , "Reluctant to work - Pythonesque Eric" , "Frivolous" .)
