One of the many ways that businesses add character to their establishments is by creatively naming their restrooms. Here are a couple spotted on the web.
I get the name "Joe" for the men's restroom (after all, Average Joe, Joe Public, Ordinary Joe and Joe Sixpack have long been used as generics to represent the average American male); what I don't get is "Sally" for the women's restroom. The female equivalent of the above named "Joes" has always been "Jane". In my experience, "Sally" is used as a derogatory nickname for effeminate men. So what gives?
Maybe it has to do with Urban Dictionary's top definition for Sally: "A really, really hot girl."
