hang-up

to squint and kind of frown as you look at your [computer] to give the illusion that you are in fact very busy analyzing something vital to your work; often used in conjunction with [paper-shuffling] and calling numbers that you know won't answer then acting really frustrated when you hang-up so that it gives the impression your chasing a very important account and have a lot on your plate already > After I [computer-faced] facebook for an hour this morning, I called a random number and talked to an older gentleman for 27 minutes about the prospect of leasing his mineral rights until he realized he didn't own any mineral rights, so I hung-up and went back to [computer-facing] a New York Times article about fashion week.
