Celebrate getting rid of junk? (4,3,4,3)
I believe the answer is:
push the boat out
'celebrate' is the definition.
(I've seen this before)
'rid of junk?' is the wordplay.
I cannot really see how this works, but
'of' could be 'o' and 'o' is present in the answer.
'junk?' could be 'h' (synonyms) and 'h' is found within the answer.
This may be the basis of clue (or it may be nonsense).
'getting' acts as a link.
(Other definitions for push the boat out that I've seen before include "Entertain or celebrate lavishly" , "Punters may" , "party?" , "A lifeboat crew may" , "launch" .)
