There’s nothing manlier than dairy, right? What could be a better display of masculinity than downing a pint of whole milk?

This is the bizarre thinking behind the far right’s new favourite insult: "soy boy".

It's becoming more widely used online and can be used as an adjective too, with people or actions being described as "very soy."

The idea is that if you drink dairy-free milk alternatives, you are obviously weak and feminine (based on the thinking that soy products increase men’s oestrogen levels, even though this hasn’t been scientifically proven).

And then there’s the fact that soy is often used as a meat alternative, and as we all know, real men eat meat. And women only ever eat sad plates of salad.

According to Urban Dictionary, the term soy boy means: “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’.”

The term has largely taken the place of the word “cuck”, which has for a while been the insult of choice of many far right people - it’s short for “cuckold” and is used to imply that a man’s wife or girlfriend is cheating on him with a more masculine male.

For the men who use terms like cuck and soy boy, being called anything related to femininity is the ultimate insult. God forbid anyone be an actual woman.

The term has become increasingly popular on Twitter, Reddit and YouTube comments, with trolls regularly criticising others they deem to be weak as "soy boys".

Where soy boy originated from, however, is unclear.

The Daily Dot suggests that it could have been started by Mike Cernovich, a far right social media personality, who’s been using the term to insult people on Twitter for months.

But YouTube political commentator James Allsup, who was caught protesting with white supremacists in Charlottesville, has claimed he invented the insult.

Outside far right communities, there isn’t much awareness of the term. But if soy boy goes the way of cuck, it could enter the mainstream before too long.

But cuck was ultimately commandeered by the general public and used as an insult against the far right, removing its offensiveness.
