Big Man On Facebook.

Someone who portays a lifestlyle and identity on Social Networking sites. Where in reality they are nothing like the person they appear to be. A problem as old as the internet itself.

Can range from listing a wide variety of Hobbies and Intrests in a attempt to look a little more intresting. To deliberate character assaination of others through a profile and status updates.
Outpourngs of praise, or efflusive birthday greetings to someone they hardly know.

When one side of a relationship breakdown uses FB to make the other look bad in front of common FB freinds

When somone lists mountain biking, climbing and camping as their intrests when the last time they did any of these activites was 1999

"John went kickboxing today it was awesome"
"Really? I heard you passed out after two push ups BMOF"
