This is a really interesting point and I'm glad I glanced at this tread because this got me thinking. Thanks!
One further note - if OP is going to classify the "unicorn" relationship because it is a stereotype, then it also seems fair to mention that it is stereotypically a m/f couple seeking a bisexual female. That detail seems too important to overlook.
