The 'Soylent' meme, commonly known as the 'Soy Boy' or 'Soylent Grin,' centers on a specific exaggerated facial expression characterized by a wide-open mouth and wide eyes. It is often used to satirize 'nu-males' or individuals perceived as overly enthusiastic about pop culture, tech gadgets, and consumer products. The term originates from the perceived connection between soy consumption and feminine traits, though the meme has evolved into a broader visual shorthand for mockable, performative excitement. It gained massive traction on platforms like 4chan and Twitter, frequently appearing in Wojak variations or photo edits to highlight perceived lack of masculinity or blind brand loyalty.
