I think the point of this isn't to create an equation that applies solely to the stereotypical man, to to all variants of Men in their Manliest forms. Take a look at Brad and Morgan. Clearly, they are different breeds of Man. Morgan is far more along the lines of a stereotypical man (or at least, tries to be), While Brad is a more elegant, high-class man. Can one say that either is more manly than the other though?
Let's take a look at the most recent revision of the Manliness Equation (Manquation?), and how it breaks down for each of them.
M=(C^R+(Ld)^P)f
Morgan
Conquest: Well, he's Morgan, don't really need to go into much detail here.
Risk: His arm's currently in a sling, 'nuff said.
Largliness: Swiss Meat Roll, the Gigantor, shall I go on?
density: Meat is dense, and Morgan knows his meat.
Pyro/Fireliness: ....Actually, don't know how much experience Morgan has with fire off-hand, so I'm goign to ignore this for now.
facial hair: Morgan has some good stubble going on at the moment, even if he lost it all during Desert Bus.
Brad
Conquest: He managed to conquer the Japanese Bureaucracy through an item quest as just one example.
Risk: He took on the Japanese Bureaucracy in an item quest, that takes serious hutzpah.
Largliness: Look at the size of his chin! Those Mandibles! Then there's his weapon collection (e.g.
this). Not to mention the extent of his knowledge and all of his stories, which leads me too...
density: Brad has an astounding amount of knowledge and awesome stories packed away in that head of his. Not to mention that steel is quite dense.
Pryo/fireliness: To make it fair, I'm ignoring this here as well. Although I'm pretty sure radioactive urine would count here.
facial hair: He had facial hair, but it coalesced into those mandibles.
