Cell Phone Silverware
The act of placing your smartphone next to your plate at dinnertime, whether actually texting someone or not, with the intention to brag about your smartphone, or because you feel the need to check the time every 3 minutes. Usually this is done by people of 16-25 years of age.
As if they had all previously agreed they'd do it, everyone at the table pulled out their Iphone 27s' and Droid R2-D2s, waved them around to let everyone know they had them, and set them down at the table to use for Cell Phone Silverware. The two crack heads in the corner were the only one's using them, and were checking the time every minute.
