A human who has been degraded by society for being too full of edamame; also known as an eDamame's boy; this degraded human is used by women and men alike to plow so that the soy boy becomes a plaything for the benefit of the more dominant. This evolved human is also known as a Chad dad or a barren Karen. Though many will use these boys many still will marry them and find an enriched life full of splendor.
What kind of men are you interested in? A man that eats his vegetables and slams this punani every night. You know, like a soy boy boy toy.
