Noun:
A person who plays one or more of the
game applications on Facebook. Usually these
people become very annoying with their constant
game posts about what they need for their Farm, Fish, Mafia, Pets, etc. Such players also tend to spam inboxes with game invites and so called "free gifts".
Joe: "Man,
Kate is really
annoying me with all her posts. I can't see the important posts on my
wall anymore because of her. She has really become a Facegamer"
Kevin: "After being laid-off for a few months, I really became a Facegamer and it kind of sucked to go back to work"
