Not just a little nip, but a proper painful-looking mouthful.
32-year-old Venezuelan model Lewin was having fun on the beach when a gang of pigs came running over to her.
The one that got to her first then bit her rear end, leaving a large mark on one cheek, prompting Lewin to run off screaming: "It bit me! It bit me!"
Lewin shared the clip to her 13.3 million Instagram followers, with over 4.5 million people having now watched the drama unfurl in less than 24 hours.
She also posted a clip of the injury on her bum, revealing a sore-looking red mark to the camera.

One backpacker has a similarly invasive encounter with a monkey recently - but unlike the pig and its cheeky nibble, this critter decided to have a grab at her top, nearly yanking the whole thing off and exposing her in front of everyone.
Los Angeles-born Brittany Bowman was travelling around South East Asia and had decided to take a trip to Chiang Mai, Thailand, which is an area that's famous for having loads of monkeys.
Thankfully, Bowman was able to just about preserve her modesty - although her friend was around to capture the drama unfold.
Bowman luckily saw the funny side of what happened, saying: "It left all of us laughing hysterically, almost to the point of tears.
"I was just so scared that the monkey was jumping on me that I didn't even consider it would pull down my top.
She continued: "The owners said he must have been looking for breast milk.
"It was all just so random, I'm just glad we caught it on camera."
