Roughly out of control in Rocky? Not Levi! (7)

I believe the answer is:

violent

I'm a little stuck... Click here to teach me more about this clue!

'roughly out of control in' is the definition.
I can't judge whether this definition defines the answer.

'rocky? not levi' is the wordplay.
'rocky?' indicates anagramming the letters (I've seen 'rocky' mean this).
'not'+'levi'='notlevi'
'notlevi' anagrammed gives 'VIOLENT'.

Can you help me to learn more?

(Other definitions for violent that I've seen before include "Extreme(ly aggressive)" , "Intensely forcible" , "Vehement; unrestrained" , "Brutal - intense" , "Marked by physical force" .)

I've seen this clue in the Irish Times.
