Soy Boy
An insult intended to equate disagreeing with a reactionary with weakness. The logic involved is something like "everyone who disagrees with me must be a tofu-eating vegetarian, and that's unmanly," often with some baseless fear-based pseudoscience about phytoestrogens tacked on after the fact. Ironically often spewed by users of nootropic pills that contain soy (and clearly aren't helping); rarely takes into account the fact that soy is a common allergen.
Reactionary: "Disagreeing with me? What are you, a soy boy?" Rational Person: "I'm allergic to soy, and it's called paying attention. And what's the first ingredient in those BranePowah™ pills you shill, again?"
