Top definition
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 modern effeminate male, typically a millennial. A self-described feminist-leftist who majored in Social Justice Studies, Gender Studies, Ethnic Studies, Theater, Dance or any other range of useless college degree fields. Shows fear and revulsion at the sight of masculine men. Usually appears in public wearing flannel, skinny jeans often of a short length to resemble Capri pants. May have dyed hair and a beard that he spends at least a half hour each morning grooming. Urinates standing up in a stall in the men's room rather than at the urinal. Has a penchant for expensive Starbucks flavored drinks with soy milk and flavored craft beer. Likely a vegan or vegetarian. Raised by dominant man-hating feminist mother either without a father or with a cuckold henpecked man for a father. May own a car, likely a Toyota Prius or Nissan Cube, but has no concept of how to open the hood or change a tire. More likely rides a fixed gear bike. Completely lacking in any mechanical skills and proud of that fact. May spends hours or days gaming in his mother's basement. Offers nothing to society.

Insult used to describe a close-minded male who seriously lacks masculinity and has leftist views, usually in a manner that annoys the hell out of everyone.

Mostly found on social media platforms, soyboys default to self-deprecation, never shutting up about politics, and labeling people with different views at least one of these names: Nazi, Bigot, Misogynist, Conservative, Fascist, Sexist, Racist, Xenophobic, Child, etc.

In short, "soyboy" means to be like Wil Wheaton.

Synonyms: cuck, nu-male, beta, virgin, omega, neckbeard, sissy, pussy, mangina, string bean, dickless.
Friend 1 to Friend 2: Hey man did you see who won the super bowl?

Both friends: Shut the fuck up soyboy.

Noun: a pejorative used by /pol/yps and other reactionaries to describe men who oppose them. Soyboys are characterized as being weak, effeminate men who lack many of the qualities that make a man. The term soyboy is considered a personal attack akin to "You're not a REAL MAN" or "You're a sissy cockboy!" The word is typically used as an insult against anyone who is left of Ronald Reagan (A REAL MAN WHO DOESN'T PRETEND). Considering the appearance of many of these /pol/yps in real life, the word is most likely projection.
Man 1: Hey man, what do you think of my beard?
Man 2: You're a freaking soyboy for not agreeing with me on how I think FEMINISM IS EVIL! And you use Discord! And other things that I don't like!

Get a Soyboy mug for your mama Nathalie.
Term associated with the mass paranoia from alt righters of being perceived as girls, mostly stemming from the constant bullying they got from bigger kids growing up and that traumatized them into being terrified of ever displayed such traits.

Usually justified with extreme levels of illiterate pseudo science like how it has been "proven" while being supported by no one with any actual degree in any relevant field.

As valid as: Flat earth, chem trails, 9/11 loose change, anti vaxx movement, etc

Another rainfall in the massive shitstorm of anti intellectualism that the outcast , unemployable manchilds of the alt right have caused.
"Man" 1: "Look at that cuck Soy Boy, you can tell he can't get his dick up because of all the soy he eats... why do the women prefer him , and everyone else, to us though? FUCKING CUCKS" (In screeching , deranged tones)

"Man" 2: "Yeah, i feel you man, can't have that happen to us. Now let's go gulp some male vitality"
