when you or someone else comments on a wall post or photo, and is meant for no reply, but you decide to reply and then they reply and it keeps going. This irritates the other people whom either left one comment or a like. Their notifications build up and they explode on you telling you and the other participator of the war to stop; which only tempts both of you to keep going until that person is smart enough to delete their comment or unlike the post in order to put an end to the notifications.
