The, sometimes involuntary, brief peek at your Blackberry, iPhone or other PDA when you are bored in a conversation, group interaction, business meeting, movie, sporting event, etc. Has the same seemingly posthypnotic contagious effect as a traditional yawn.
Guy #1:"Seriously, did someone just call you guys, or was that a PDA yawn?"
Guy #2:"Sorry, I just lost focus when you were talking about your Bijon Frise rescue dog."
Guy #3:"Oh, uh, sorry dude."
