He wanted a “yes” but got a drippy mess.

Waterside “will you marry me” moments are great — in theory. But when the ring hits the water, that’s when the you-know-what hits the fan.

“Oh s–t,” sighed the bride-to-be after accidentally knocking her still-boxed engagement ring out of her fiancé’s hand and into a shallow lake.

Footage of the guy’s sweet-turned-soggy proposal, made viral by NYC model and his soon-to-be sister-in-law McKenna Hiller, shows his face dropping as the rock rolled off the dock and into the wet stuff.

“This was typical of us,” the laughing groom-to-be said right after a beer bottle was also knocked over on the dock.

The shocking snippet scored a staggering 647,000 Instagram views, which prompted congratulatory cheers from fans and side-eyes from skeptics — many who believe the future bride’s diamond-dunk was no silly accident.

“She didn’t want to marry him and tried laughing through [it]feeling awkward and not wanting to say ‘No’ on camera,” argued a cynic in the comments.

“How sad,” wrote another. “Dude doesn’t even realize he’s been in the friend zone this entire time.”

Trolls, too, scolded the man for setting himself up for a splashy disaster.

“Can we PLEASE stop proposing over bodies of water,” carped a critic.

“Why do people still propose on piers [and] docks,” questioned an equally underwhelmed onlooker. “We’ve all seen this happen.”

And they might be right.

Katie Nicholson, 24, found herself on an “emotional roller coaster,” after briefly losing her square-cut gem to the ocean following fiancé Steve’s big ask in July.

Thanks to a kindly passerby, the precious stone was quickly retrieved.

Zay, an Australian groom-to-be, arranged an elaborate engagement scene for fiancée, Sai, on Sydney’s Coogee Beach ahead of Valentine’s Day 2023 — only to lose the bling-bling in the sand. Online onlookers deemed the shoreside proposal “a nightmare.”

And Ross Bamber, 26, from the UK, said his heart dropped after hearing the $1,200 ring he’d just presented to then-girlfriend, Geri Ashforth, 23, plop into a lake before he could even drop down on one knee.

“I took the ring out of my pocket and as I opened the box the ring fell out,” he recalled in 2022. “It bounced a couple of times and then fell between the gaps of the decking.”

Ashford later took to social media, announcing that despite her and Bamber’s best efforts, “our ring has been lost to the lake forever.”

However, Hiller, who captured the latest mishap on video, wasn’t willing to let her big sister and brother-in-law-to-be suffer a similar fate.

Seconds after the twosome’s token of affection made a splash, the Big Apple beauty leaped into the water and saved it from sinking.

“Not it floating PERFECTLY,” Hiller gushed of the buoyant bijou. “And not my instinct as the little sister to jump right in.”
