A threesome that involves one member of one gender and two bisexual or pansexual members of the other (or some weird combination of pansexuals if enbies are involved.)

The idea is that, to bi/pan people, it's slightly superior to a gay threesome, because two of them get a more varied experience, and that it's WAY better than a traditional threesome with straight people, as all three of them get to enjoy two partners rather than just one of them.
Luke: "I had a threesome last night."

Charlie: "Oh how was it?"
Luke: "The guy was bi, so it was a max potential threesome. Incredible. I got fucked in the ass and fucked this girl's pussy at the same time. Scratched two itches at once."
