Stop bucketin' down, by the sound of it (4,2)
I believe the answer is:
rein in
'stop' is the definition.
The answer and definition can be both to do with social activities as well as being verbs in their base form.
Perhaps there's a link between them I don't understand?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for rein in that I've seen before include "Person of great power" , "Control" , "Restrain (someone)" .)
