Spread sloppily (5)
I believe the answer is:
smear
'spread sloppily' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for smear that I've seen before include "Greasy or sticky mark" , "Medical examiner may take this" , "Unwarranted accusation" , "Spread dirty substance, try to damage reputation" , "Sully" .)
