See unruly boy initially on cart flipped, streaking round (6,6)

'see unruly boy initially' is the definition.
I can't judge whether this defines the answer.

'on cart flipped streaking round' is the wordplay.
'on' becomes 're' (regarding).
'flipped' says the letters should be written backwards.
'streaking round' becomes 'bullet' (I can't justify this - if you can you should give a lot more credence to this answer).
're'+'cart'='recart'
'recart' written backwards gives 'tracer'.
'tracer'+'bullet'='TRACER BULLET'

Can you help me to learn more?
