Shoot shag off-limits, causing uproar (3-2)
I believe the answer is:
hoo-ha
'uproar' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for hoo-ha that I've seen before include "Commotion (informal)" , "Noisy fuss" , "Kerfuffle" , "Disturbance" , "great deal of fuss" .)
