When you access your computer without sitting down at your desk, using the keyboard and or mouse with your arms extended over the chair. Usually used with the presence of mind that you will not be committing to an extended period computering.
Mom: John, I told you to shovel the driveway, you better not be on your computer!

John: Wtf! Relax, I'm over the chair right now..
