'Go away!', you broke in rudely (2,4,4)
I believe the answer is:
on your bike
'go away' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'you broke in rudely' is the wordplay.
'rudely' is an anagram indicator.
'you'+'broke'+'in'='youbrokein'
'youbrokein' is an anagram of 'ON YOUR BIKE'.
Can you help me to learn more?
(Other definitions for on your bike that I've seen before include "Scram!" , "Get away!" , "mocking dismissal" , "Clear off! (slang)" .)
