A Bean Complex is when a person, normally a male, develops an attachment to a possibly sexual event involving a specific person. He then proceeds to never let go of this memory, seeing as it may very well be the last event like this he/she will ever experience, and shares it with as many people as he/she possibly can, including the person involved in the event.
James: Dude, Jack has developed such a bean complex for what happened with Alice last night.

Jack: Hey guys! Remember that time with Alice when we "high-fived" all night? Good times.
John: *sarcastically* Yeah, really cool.
