The Moustair meme, a portmanteau of 'moustache' and 'hair,' features a surreal image where long hair is styled or manipulated to appear as a massive, overflowing mustache on a person's face. Often utilizing a perspective trick where a person leans their head back and pulls their hair forward over their face, the trend gained traction on image-sharing platforms like Reddit and Tumblr during the early 2010s. It represents a subgenre of internet humor focused on bizarre physical transformations and optical illusions. Today, the Moustair remains a classic example of low-budget, creative internet weirdness, used primarily to express over-the-top masculinity or simply to confuse and delight viewers with its hairy absurdity.
