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

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

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".

Mantis and my brother John. Although they're very much gay, both are still soy boys that plan to ride off to australia together. This doesn't just apply to them though. Technically, most soy boys aren't gay yet are also very pro-feminism. They dislike communist (one thing Mantis doesn't have in common with the common soy boy) and would totally marry the first girl they drunk fuck at a frat party that they didn't get invited too.
Me : John, you and your gay boyfriend are such soy boys. Worse than Carl Wheezer and his croissant loving-ass.
John : lol nah fam no homo bro
Mantis : lmao k
