Stagger round for a bit of fun and get some more juice (6)
I believe the answer is:
refuel
'get some more juice' is the definition.
I can't judge whether this definition defines the answer.
'stagger round for a bit of fun' is the wordplay.
'stagger' becomes 'reel' (both can mean to move around without balance).
'round' indicates putting letters inside.
'a bit of' indicates taking the first letters.
'fun' becomes 'u' (I can't justify this - if you can you should believe this answer much more).
The initial letter of 'for' is 'f'.
'f'+'u'='fu'
'reel' placed around 'fu' is 'REFUEL'.
'and' is the link.
Can you help me to learn more?
(Other definitions for refuel that I've seen before include "Fill with petrol again" , "Fill the tank again" , "Stoke up again" , "Fill up the tanks" .)
