An AOR typically resorts to constant emoticon usage, often ending his posts with a face_laugh with the assumption that this helps him win his arguments, even when the straight man doesn't bother arguing in the first place.
An AOR can be easily irritated when, in response to a particular instigation, the poster who is the focus of an AOR's current attack simply copies and pastes a previous response repeatedly.
Oh, that's AOR. Don't mind him. He doesn't know how to let things go.
