Escaping confines, male bear back in uproar (4-2)
I believe the answer is:
hoop-la
'uproar' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'escaping confines male bear back' is the wordplay.
'escaping confines' becomes 'h' (I can't explain this - if you can you should believe this answer much more).
'male' becomes 'Al' (shortened version of Alex or Alistair).
'bear' becomes 'poo'.
'back' shows that the letters should be reversed in order.
'al'+'poo'='alpoo'
'alpoo' written backwards gives 'oopla'.
'h'+'oopla'='HOOP-LA'
'in' is the link.
Can you help me to learn more?
(Other definitions for hoop-la that I've seen before include "Throwing fairground game" , "Game in which rings are thrown over objects in order to win them" .)
