noun. Macho headgames, ultimate fighting, or other testosterone-propelled stuff.
Real citation: "Of course, there's the literal balls in the movie: every guy's nuts being blown off or ripped out. Then there's the testosteroniness of the movie, with every guy narrating his macho philosophy and every woman being a hooker or stripper."
Made-up citation: "A blood test detects testosterone, but testosteroniness is usually manifested in wardrobe and DVD collections."
