A term used by insecure men who think you're not a true male unless you're beating your wife into submission or catcalling underage girls on the street. Likely, these specimen are frustrated by being incels (involuntary celibates) or for generally having less sex than the Soy Boys, so they lash out by insulting them with food names.
Typical incel: Have you seen that Soy Boy? He actually respects women, what a pussy!
Normal Person: No wonder women don't want to have sex with you.

A word that make me loose faith in humanity when I look the other definitions on Urban Dictionary.
Soy Boy is a stupid-ass concept. I really loose confidence in all of Homo sapiens when I see that a man should "be muscular, fight, know how to repair a car, not be feminist".

Get the Soy Boy mug.
Slang used to describe males who completely and utterly lack all necessary masculine qualities. This pathetic state is usually achieved by an over-indulgence of emasculating products and/or ideologies.

The origin of the term derives from the negative effects soy consumption has been proven to have on the male physique and libido.

The average soy boy is a feminist, nonathletic, has never been in a fight, will probably marry the first girl that has sex with him, and likely reduces all his arguments to labeling the opposition as "Nazis".

Get the Soy Boy mug.
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?"

A Soy Boy is a guy that will do anything for a female for free. If you give a girl that you aren’t dating a free ride you are classified as a Soy Boy. This includes letting them mooch off your Juul or Sourin.

A soy boy is a boy who is made out of soy
A boy who is soy is often ridiculed for his man tits but doesn't care because he knows deep inside of his heart that his man tits and soy food neck are beautiful.

Soy boys are always going to be there for you, for that is part of the soy boy code of honor or the soy commandments.
