When someone stalks you on Facebook. And when you actually meet them they start saying random things that they know about you; such as your birthday, exact height, school, after school activities, and address. If this happens, then you've been Stalkerbio'd.
They often deny Stalkerbio-ing you.
Suzy: Hi Dave.
Dave: Hello Suzanne Anne Anderson, born on December 8, 1995, in Lawrence, Kansas. Who is now 5 ft 5 inches, and lives on 555 Bieber Lane.
Suzy: Ohmygosh, I've been Stalkerbio'd.
Dave: What are you talking about? I'm not a stalker... By the way do you still swim on Tuesdays at 3:30 pm?
