Extra swell for everybody? (2,4)
I believe the answer is:
no ball
'extra' is the definition.
(I've seen this before)
'swell for everybody?' is the wordplay.
'swell for' becomes 'nob' (I can't explain this - if you can you should give a lot more credence to this answer).
'everybody?' becomes 'all' (I've seen this before).
'nob'+'all'='NO-BALL'
Can you help me to learn more?
(Other definitions for no ball that I've seen before include "bad delivery" , "Illegal delivery" , "Disallowed delivery" , "Extra in cricket" , "Botched delivery" .)
