Is this what it means to be the butt of the joke?

A big-hipped TikToker has gone viral for revealing the ultimate party trick: Stowing bottles of alcohol between her butt cheeks.

Steph Oshiri shared her unique talent with her 210,000 followers, and ever since, the OnlyFans model has posted a slew of clips featuring the junk she can fit in her 55-inch trunk.

“I wish I was joking,” she said with a short laugh while revealing her ability in a clip with more than 470,000 views.

While it’s “humiliating,” she admitted in the caption, she explained that it allowed her friends to drink cheaply.

In a video demonstrating just how she makes the sizable glass bottle disappear, she called it her “party trick.”

“POV: you ask me for a drink at a concert and I pull this baby out from between my cheeks,” she wrote on another TikTok, seemingly pulling a bottle of whiskey from her behind.

Her baffling fete shocked her followers every time, while some joked that it was “bottle cervix.”

“No way,” one astonished user wrote.

“I have so many questions,” another chimed in.

“That’s a talent,” someone added.

“Liquor is liquor,” wrote one viewer.

“That has got to be uncomfortable though right?” someone else commented.

In later clips, she proved she can fit more than just a glass bottle, including miscellaneous objects like cigarette lighters, books — and even a sword.

The OnlyFans model previously claimed she was racking up between $2,000 and $3,000 every month with her revealing content on the subscription platform.

“My body stands out. Obviously, the majority of my audience subscribes to me for my wide hips and bum. I definitely don’t think I would be as successful if my bum was smaller,” she once told Jam Press. “I have my 55-inch booty to thank for my $45,000 a month paycheck.”

And, apparently, a cost-effective way to drink.
