I ain’t get my bike back, I know where he live at
I know what he look like, I know what I live like
Childish is describing a story of when he got his bike stolen when he was a kid. In most cases, many wouldn’t know who had their bike stolen otherwise they would go get it back, but Donald knew who the thief was and where he lived but knowing the type of person he himself was (nerdy, poor, chubby), and although he was poor and (literally) couldn’t afford to lose it, he didn’t have the courage (or the muscle) to go and retrieve the bike back.
