A person who consumes soy products and usually has a man bun and a scarf/skinny jeans. They typically get around on a bicycle but sometimes use a trike or a hover board. Soy Boys are extremely skinny and unmasculine because of all the soy consumption. Some may even grow boobs if enough soy is eaten.
Person 1: I'm gonna go to the human bean and get some iced soy latte coffee and then im gonna go to the co op and buy some farm fresh almond milk and soy beans. After that im gonna go on a nice little ride up into the mountain trails on my bike.

Person 2: Shut the fuck up, soy boy.
