The act of rolling under your desk while at work to take a nap. An overwhelming feeling of sleepiness comes over you and the need for a resting place (under your desk) is inevitable.
Typically this works for employees with offices, not a cubicle. To avoid suspicion it is best to leave your door open, turn off your lights, and move your laptop (if you have one) under your desk with you so that everyone thinks that you are gone. Secret compartments to hide your belongings (jackets, hats, or whatever else might give you away) are not necessary, but can be very cool. This maneuver is not recommended for those that snore.
Employee 1: "Dude, I thought you had left for the day..."
Employee 2: "Nah, I did a desk roll after lunch. I couldn't stay awake after my Thai lunch."
