Boy I trick, say, over ending a race (9)

'boy i trick say over ending a race' is the definition.
I can't judge whether this defines the answer.

'boy i trick say over' is the wordplay.
'boy' becomes 'lad' (informal term for boy).
'trick' becomes 'con' (a con is a fraud or trick).
'say' becomes 'eg' (both can mean 'for example').
'over' says the letters should be written in reverse.
'lad'+'i'+'con'+'eg'='ladiconeg'
'ladiconeg' back-to-front is 'GENOCIDAL'.

Can you help me to learn more?
