ABA CAD 

When you're writing a multiple choice test and have no fuckin idea what any of the answers are, so you use "ABA CAD" to get through it. First question, you answer A, then B, then A, then C, then A, then D and repeat until the test is over. At least some of your answers will come out right (hopefully)

Rob: "shit man, I was ripping up a bar last night and I'm blanking on this test right now"

Milos: "Just use ABA CAD. That's always helped me push through"

Desperate means used when you have not studied for a test. On a scantron, you pull the ol' "ABACADABA" and fill in those letters accordingly in hopes of passing the exam.

man 1: How do you think you did on the exam?

man 2: I didn't study, I pulled the ol' ABACADABA.

A drunk magician's magic word.

"ABACADABA!" cried the magician.

Then the earth exploded.
