Dispose of bushy hair — revolting! (3,2)
I believe the answer is:
mop up
'dispose of' is the definition.
(I've seen this before)
'bushy hair revolting' is the wordplay.
'bushy hair' becomes 'mop' (I've seen this before. I am not sure about the 'bushy' bit.**).
'revolting' becomes 'up' (I've seen this in other clues).
'mop'+'up'='MOP-UP'
Can you help me to learn more?
(Other definitions for mop up that I've seen before include "polish off" , "Deal with spillage or defeated enemy" , "take care of" , "Complete final stage (of a task)" , "Kill (enemy stragglers)" .)
