A set of twins or best friends, where one is blonde and the other brunette. They get along very well and have tons of fun times; in fact, they are known as the best people to hang out with! They have great talks and even write notes to each other during school, often including their multiple inside jokes.
Boy 1 - "Have you seen the Bobsey twins? They're looking foxy, as usual."

Boy 2 - "Yeah, dude, gotta love 'em!"
