The stereotypical 'nice guy' in every class. He's nice, attractive, and has an average sense of humor. A 'Jaeridan' plays a typical sport like football or something equally common. A 'Just Jaeridan' can be anybody - your average looking neighbor, your Dad, your Mom. Anyone. 'Jaeridans' are usually background people.
Girl: Hey, who was that guy? He looked pretty nice.
Girl 2: Yeah, he was, but he was a total 'Just Jaeridan'. I might call him; I might not.
