Justine Kish had just finished a grueling 15-minute fight with Felice Herrig, which she knew would result in a loss, when suddenly the smell hit her.

“The bell went off, and I noticed something,” Herrig said Thursday on “The Domenick Nati Show” on iHeartRadio. “I was like, ‘What is that smell?’ I’m thinking is it the referee? Did he pass gas or something? And I look on the floor.”

That’s when she saw it. The poop smeared on the mat.

“I knew it wasn’t Felice,” Kish said. “I see myself, and I’m like, ‘Oh no. Oh my God, that’s me.’ And then I’m thinking do I clean it up? What do I do? I look at my corner, I’m pointing, and I’m like, ‘That’s my (expletive) on the floor.’ …

“You’d think I would feel it or something, but no, I was too busy getting the (expletive) choked out of me.”

Kish admits the unfortunate in-cage accident at UFC Fight Night 112 over the weekend “humiliated” her immediately upon realizing what happened. All she wanted to do in that moment was leave the cage.

“Defense mechanism is to leave and clean yourself up,” Kish said. “But it would be very rude to do that.”

So she stood around, with poop in her shorts, and waited until Herrig got her hand raised. Kish said tt felt like forever and once the announcement was made, she made a bee-line for the locker room.

She realized backstage there was no sense in hiding from something everyone had noticed. So she owned it with a post-fight tweet poking fun at herself. Kish made light of a crappy situation and continues to be a good sport about it.

But what did she eat on fight day to cause this?

“Maybe I had a little bit too much fiber,” Kish said. “I had steel cut oatmeal, bacon and eggs, and water, and refuel packs to hydrate. I probably had like a hundred bottles of water just because I had to lose so many pounds. I swear, I promise – I went to the bathroom like 20 times. That’s all part of pre-fight stuff. I didn’t think anything was left in my system.”

It happens. The good news is some unexpected opportunities are on the table for Kish, who said she’s been approached by DUDE Wipes, a disposable wipe product company featured on “Shark Tank,” with a sponsorship offer.

“I’m actually considering it,” said Kish, who adds she’s also “not above” doing an adult diapers pitch. “Because, you know what, we could have some fun with this and maybe make the product less embarrassing or more funny. You know, if it puts a smile on someone’s face.”

That’s the attitude.
