The
act of completely being fixated on your smart phone/device in a public place,
esp. when you sitting with at least
one other person.
Look around at any restaurant or
bar. There's always one table full of
people who are all completely engrossed in their smart phones. When you see your date/spouse/significant other checking a social network on their phones as they sit at a table/bar with you, tell them to "stop droning". I have told the
people I am sitting with (at lunch) that I'm "checking out" and am going to drone for a while.
