An individual with an often mysterious past. Half of the time people assume it is because he has nothing going on. The other half of the time they believe he is some sort of superman because of everything he seems to have his hand in.

Either he is a complete sham, or a completely unique individual.
Guy A: "Dude, how the fuck did Deemer win the awards for physical fitness, intelligence, and aptitude?"
Guy (but usually Girl) B: "I don't know man, he's probably just a solid guy."
Guy A: "I think he's cheating."
Guy/ Girl B: *to themself* "At least he doesn't need to compensate for something by being jealous."
