Jump over the thing and buzz off (3,2)
I believe the answer is:
hop it
'buzz off' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'jump over the thing' is the wordplay.
'jump over' becomes 'hop' (I've seen this in another clue).
'the thing' becomes 'it'.
'hop'+'it'='HOP IT'
'and' is the link.
Can you help me to learn more?
(Other definitions for hop it that I've seen before include "Clear off!" , "get out quick!" , "Leave" , "split" , "On your bike!" .)
