facegeek
A facegeek is someone who spends more time on Facebook than they do in real life. They would rather fight with their ex on Facebook than talk to them in person.
I got into a 2-hour argument with my cousin over a post about pizza.
I posted a status saying 'I hate my life' and 12 people replied with 'me too.'
I woke up at 1 AM to reply to a message from a person I haven't talked to in 5 years.
