Perfunctorily execute rogue (5)
I believe the answer is:
scamp
This clue is a double definition.
'perfunctorily execute' is the first definition.
(scamp can mean to do something perfunctorily)
'rogue' is the second definition.
(I've seen this before)
(Other definitions for scamp that I've seen before include "little monkey" , "Scoundrel" , "A young rascal misbehaving in camps" , "Troublemaker" , "Mischief-maker" .)
