It's not what you think, but exactly what you expect.

Expecting an outcome but being surprised on how it comes to be.

Morty: Aww geez Rick, what are we gonna do?

Rick: I don't know Morty, I mean this entire situation is a horse fire.

Morty: A what?

Rick: It's a horse fire morty, I mean I expected these Mongoloid Raptors to try and kill us, but I didn't think they'd use sardonic malorganite to try and do it. This is bad Morty. Real bad.

Morty: I still don't understand where the horse comes in?

Rick: Priorities Morty! Space raptors are trying to kill us with one of the universe's deadliest weapons and you're still hung up on grandpa's vocabulary!

Morty: Yea but..

Rick: But nothing Morty!! It's a real phrase!! You can look it up on Urban Dictionary if we make it out of this horse fire of a situation!!
