A man who comes from another planet; unlike Mars where most men come from and Venus where most women come from. These men don't subscribe to the typical man/woman dynamics in relationships and have unique belief systems and behavior practices regarding women and the courting relationship. In addition, they tend to not follow proven practices that work in any form regarding females, business or life in general and pave their own way. Most of the time, they cause a decent amount of chaos in the process of working towards a goal but inevitably reach the end goal successfully. They carve their own path in life and confuse everyone in the process causing many to adopt excessive drinking habits to cope with the confusion. These men do it the hard way, but their own way.
"Why is he making things so difficult? Oh, he must be a plutonian man!"
