The act of pretending to study for a test such as the SAT but actually playing Sims 3 with all volumes off. Usually results with bad reflexes when someone walks in the door to see your SAT book closed and your face on the screen. It usually causes an awkward moment, stuttering and a bad lie which gets you in even more trouble.
