To have someone tell you that you look like a member of the cast from The Twilight Saga film series. It usually happens in cycles, and most often when unexpected. A true twidentification must be spoken, but in many cases the subject might just get stared at. Stares should only be counted when they fit into a cycle of true Twidentifications.
old lady: excuse me young man, has anybody ever told you that you look just like that guy from the Twilight?
young man: why yes, I have been twidentified many times before, but never at my grandfathers funeral!
