Manbabies is a surreal internet phenomenon that gained massive popularity through the website ManBabies.com, launched in 2008. The concept involves digitally swapping the faces of an adult man and an infant, usually a father and son, resulting in a bizarre and often unsettling 'uncanny valley' effect. While it started as a simple Photoshop trend, it evolved into a broader meme category used to satirize men who refuse to grow up or to highlight the comedic likeness between parents and children. Today, the Manbabies template is a staple for those looking to create unsettlingly funny content that plays with proportions and biological expectations.
