An expression which originated during a drunken late-nite discussion of the origins of expressions. It means, "I see what you're saying, where you're going with that."

Drunk person A: "Dude, you know what I mean?!"

Drunk person B: "Totally, Dude. I'm riding that train, reading that book."

I'm riding that train, reading that book. . . 

Same as saying, "I feel you."

Cooler Person B: "Yeah, man. I'm riding that train, reading that book. . ."
