Basically used against any male who isn’t masculine or not aggressive enough to be a “real man”. It came from teenage boys thinking soy sauce on their chinese food is going to make them effeminate and gay. They have an obsession with feminine boys at their school because real problems like the current state of the economy are mommy and daddy’s business.
Guy 1: I think I’ll go shopping at Forever 21

Guy 2: HAHAHA SOYBOY!!1!

Guy 1: But the chinese food you’re eating has soy sauce! *pours it on the rice*

Guy 2: AAAAA!! *runs away*

A term used to derogatorily define a man who preaches for progressive ideals such as feminism, racial tolerance, social justice, etc.

It stems from the myth that eating soy increases the amount of estrogen present in the body and that it somehow brainwashes men into becoming progressive.

Tucker: "He's such a feeble soyboy, of course he's defending those fags on the streets."

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.
