For those who have braved hot, humid days or tight pants, “ass cheese” is an all-too-familiar byproduct — the unofficial term for the uncomfortable buildup of sweat, skin oils, and bacteria that can collect between the thighs. While not the most glamorous of topics, hygiene experts want people to know there’s a silver lining: it’s technically non-dairy.
Despite the unappealing name, this bodily byproduct is simply a result of sweat and friction, not unlike how some foods ferment. Dr. Amy Caldwell, a dermatologist specializing in skin health, explains, “It’s just sweat and natural oils that accumulate, particularly in areas with less airflow. It’s a part of the body’s cooling system, albeit an unglamorous one.”
Many find humor in the term, and online forums are packed with hygiene advice on managing “ass cheese” — from powders to breathable fabrics. And dermatologists agree that proper care can make a difference. “Keeping the area dry and using natural fibers can prevent buildup,” Caldwell suggests. “It’s a common issue, especially during warmer months or long days on your feet.”
Though it may never appear on the shelves as a trendy product, the normalization of discussing body quirks has brought a surprising community together. “People are just glad to know they’re not alone,” says Caldwell. So while “ass cheese” may never sound appealing, at least it’s a reminder of the shared experience in human biology — and, thankfully, dairy-free.
