Boisterous, disobedient (6)
I believe the answer is:
unruly
I believe this is a double definition.
'boisterous' is the first definition.
(synonyms)
'disobedient' is the second definition.

(Other definitions for unruly that I've seen before include "Rumbustious" , "Not easy to control, disorderly" , "Obstreperous" , "Disobedient or disorderly" , "Noisy and undisciplined" .)
