While we do admit that cellphone tech posts do make their way around here pretty often, this one's a little different. This one's actually about avoiding your phone, especially during dinner with friends. It's called "phone stacking" and here's how it works: everyone places their cellphones facedown on the table (you can stack them for more suspense), then the rules are simple, first person to pick their's up to check for missed calls or messages pays the tab. Sounds easy enough, right? Go for it on the next night out with amigos. We pretty much guarantee a fun time!
