Go for drinking session and almost score (3,3,3)
I believe the answer is:
hit the bar
'go for drinking session and almost' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'score' is the wordplay.
I cannot quite see how this works, but
'score' could be 'hit' (synonyms) and 'hit' is present in the answer.
The remaining letters 'thebar' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for hit the bar that I've seen before include "Narrowly miss scoring" , "go for a drink!" .)
