Bug lashes out (6)
I believe the answer is:
hassle
'bug' is the definition.
(I've seen this before)
'lashes out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'lashes' anagrammed gives 'HASSLE'.
(Other definitions for hassle that I've seen before include "Lashes (anag)" , "Difficulty - dispute" , "Hound" , "Nuisance, bother" , "Informally, annoy or harass" .)
