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.

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".

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.
Show your soy boy some love
Guy 1: Bro I ate so much soy foods, I might be a soy boy now... I also grew soy packages...
Guy 2: Don't worry bro.
Guy 1: I DON'T WANT TITTIES GROWING ON MY BALLS
Guy 2: Bro chill, it's all good.

Men (and some women) who constantly deem everything that is remotely inclusive as the SJW agenda or people being feminazis. These people go but of their way to be annoying, nasty, rude, vulgar, etc. They are unprogressive and blame everything on the SJWs, even though soy boys are the reason why SJW's exist. Hate identity politics, but tend to talk about them a lot. Especially when involving their favorite superheroes. They promote their own agenda, then blame it on the SJWs. SJWs are bad, but soy boys are worse.
Person 1: Did you watch Captain Marvel? I liked it.
Person 2: HELL NO! CAPTAIN MARVEL IS GIANT FEMINAZI, INCLUSION DOESN'T MATTER! ONLY WHITE STRAIGHT MEN BELONG ON OUR SCREENS. GET LARSON OUT OF HERE! CRUCIFY ANYONE WHO SAYS OTHERWISE! REEEEEEEEEEEEEEEE!
Person 1: *facepalms* OMG, why are we friends? You are such a fucking soy boy.

A man who can acknowledge the harmful effects that living in a culture with patriarchal values, white supremacy, and transphobia has on our society, and has the confidence to go against the grain and stand up for what is right, despite a bunch of Chad’s screaming “Let’s go Brandon!,” ODing on Ivermectin, and trolling feminists in their mom’s basements, trying desperately to emasculate them, due to their underdeveloped prefrontal cortex and crippling insecurities.

Since soy has a lot of estrogen in it, and estrogen is the girl hormone, of a boy eats enough of it, he can become gay. So a soy boy in a gay boy
