You was snapping pimp, but I don't know what happened pimp
Shit changed, you ain't been the same since the accident

Man you said I was the best

But now I ain't that convinced

Meaning

The guy Cassidy is talking to (either his subconscious mind or Shyne) doesn’t think he’s hot as he was before the accident

This isn’t the first time Cassidy references the accident affecting his rap game;

Get the obituary ready, get the Reverend
My old style died, and went to punchline Heaven
You cats know that that’s my flow, I’m a legend
