Facebook comments written by a girl on her boyfriend's wall to let other girls know he's taken or to mark her territory. This may start a wall pissing war between two or more girls who like the same guy.
I'm having a wall pissing war with some chick named Dawn on Tyler's Facebook wall. I commented that I can't wait for our Las Vegas trip.

She commented right after: last night was sooo much fun ;-)

OMG! Who the hell is this bitch?!? My next comment will be: Don't forget to bring a bottle of wine tomorrow night. I'm cooking up something special...muah!
