Woman writing lengthily for The Atlantic doesn't seem to know the word "underpants."

Sarah Fentem goes on at bizarre length about how much she dislikes the word "panties." After extensive blah blah blah, she gets to this:

So what word could be used instead? Personally, I've always just called my bottom unmentionables "underwear." My sister, though, disagrees. "Underwear" is no dice, she says, because women have two types of underwear (bras and panties)—and how will you know which ones are being referred to?

Another friend of mine has suggested the terms "top undies" and "bottom undies," but I don't see that particular strategy catching on, either....

It's well-documented that women are ahead of the curve when it comes to linguistic ingenuity....

Oh, yeah, women... they're so verbally proficient that they don't know the word "underpants."
