Using Facebook whilst driving, usually in violation of state or local laws and with total disregard of the safety of yourself and others.

A person who doesn't realize they are transgender yet, or is in denial; an undeveloped transgender person. When they realize, it's referred to as the "egg cracking."

Similar to that of drink driving, but driving whilst using facebook. Face-driving is becoming more common in today's society and is hard to enforce especially when you have a good reason to be on facebook while driving making it hard for police to do anything at all as they do it themselves and completely understand you must constantly check status updates regardless to avoid becoming a social hermit. It's just the way things are these days.
