When you covertly text message with someone in your immediate vicinity because you don't want other people in the area to hear what you're saying.
My girlfriend and I were out to dinner and we started table texting about the stupid people sitting next to us.
When people covertly (or not) text message someone in their immediate vicinity because they are lazy, strange, or don't want other people knowing what they're talking about. - Most often noticed occurring in restaurants after the clubs/bars close (like iHop, Denny's, Truck Stop, etc...)
I can't believe Robert is texting that girl sitting across the table from him, instead of just talking to her. But remember, he is the King of Table Texting.
