Make a fuss then keep going (5,2)
I believe the answer is:
carry on
'keep going' is the definition.
(I've seen this before)
'make a fuss then' is the wordplay.
'make' becomes 'carry' (carrying is a kind of making).
'a fuss then' becomes 'on' (I can't explain this - if you can you should believe this answer much more).
'carry'+'on'='CARRY-ON'
Can you help me to learn more?
(Other definitions for carry on that I've seen before include "wage, or > make a fuss?" , "Have an affair - cause a fuss - continue" , "film series" , "Continue - make a fuss" , "play around" .)
