As with all batsh*t Internet trends it’s difficult to chase the origin. This one seems to have come off the back of a video uploaded to Facebook in which a woman talks about her clean underwear.

The video has sparked a conversation around vaginal discharge and in celebration of not having any, people have taken to social media to share images of their underwear, clean and free from stains.

The only problem is that vaginal discharge is completely healthy and in fact, it’s probably a more worrisome sign if you don’t have any. According to WebMD, vaginal discharge is perfectly normal. The amount can vary, as can odor and hue (its color can range from clear to a milky white-ish), depending on the time in your menstrual cycle. For example, there will be more discharge if you are ovulating, breastfeeding, or are sexually aroused.

@AsToldByBrina women need to educate themselves about their vagina . If you don't have discharge GO TO THE DOCTOR. pic.twitter.com/VxaMSxo2Zr — Taylor ❤️ (@______tlg) June 29, 2016

Thankfully, Twitter users were quick to point out the facts.

So apparently the #pantychallenge is a thing because people want to once again shame women into thinking healthy bodies are gross as hell. — Jim Avery (@TheSoundDefense) June 30, 2016

This #pantychallenge is ridiculous & was clearly started by teenagers who know nothing about how the human body works. Go see a doctor #wut

Y'ALL NEED TO STOP ! #PantyChallenge — ✨✨ JANIAH ✨✨ (@badgyalniah) July 4, 2016

I'm sad for the yng women of the #PantyChallenge who don't understand their own bodies. Secretions are NORMAL. Dry panties? Talk to your dr!

I don't care to see what the inside of your panties look like. It's really ridiculous.? #pantychallenge — Sema Tukaç (@sematukac) July 4, 2016

Like I keep saying, self-hate is so real. This #pantychallenge is women with internalized misogyny participating in their own oppression ?

Can we have, like, 5 minutes where we don't shame the perfectly normal, healthy bodies of women because that would be A+ #pantychallenge — Sophie | MILKPOP (@milkpopblog) July 1, 2016

After all, it serves a purpose.

Discharge is great. I can tell where abouts I am during my cycle by looking at my knickers #pantychallenge
