The only thing I know for real

Used to describe a situation that you don't understand, but also want to sound really damn cool.

Person 1: "Man this math test is way too hard. The only thing I know for real is that there will be bloodshed."
Person 2: "What?"
Person 1: "THE MAN IN THE MIRROR NODS HIS HEAD"
Person 2: "Bro stop fucking screaming, you're just solving for x."
