You may unfriend people every day and that may not cause problems. But for many friends, unfriending someone on Facebook is grounds for a serious talk. But for one Florida couple, having bad Facebook ettiquette led to a visit from the police.

Apparently a woman was upset with her live-in boyfriend so she unfriended him and changed her status to single. The boyfriend (or ex, as it were) got so mad that a fight broke out and things got so heated that the cops had to come and the two of them landed in jail. Lovely right?

Have you ever gotten in a fight that started on Facebook? What are some of the FB rules you wish more people would follow?
