look up any word, like blumpkin:
 
1.
when someone drives a car without hubcaps, they are "ridin' on cinder(block)s"
"I saw Pedro's new car today, and it was a real piece of junk!"
"Really?"
"Yeah, he was ridin' on cinders."

Jose thinks he is hard in his clunker, but we all laugh because he is ridin' on cinders.
