Laze around (4)
I believe the answer is:
loaf
'laze around' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for loaf that I've seen before include "bloomer, perhaps" , "Half of one is better than none" , "Head (slang) -- be a slacker" , "Head - bread" , "Some bread; 10 (slang)" .)
