Blue Waffle is a fictional sexually transmitted infection (STI) that’s believed to both turn the vagina blue and disfigure it. It’s also said to originate from women who “get around” and/or their lack of hygiene. People say it only transmits from women to men, but it only made up and not a true disease.

The myth of the disease was disproven in 2011 by the Women’s Health Foundation and proven to come from a fake photograph.
