YOU would cry too if this happened to you. And probably scream.

This girl was dumped on her sweet 16th, but not in the way you’d expect.

About 40 people had gathered to celebrate Jacinda’s birthday in the backyard of her home in Levittown, New York.

Some were swimming, while other were playing games. And then it started raining. But it wasn’t normal rain. It was brown “rain”.

“Out of nowhere, from the sky, comes a bunch of faeces, lands on her,” stepfather Joe Cambray told FOX 29.

Luckily most of it landed on a canopy in the backyard.

“We just got done with cake thank God, we took the cake back in, because within two minutes, something fell from the sky, it was brown, it was everywhere, it got on everything,” party guest Kristie Rogy said.

They used an app that showed five planes were above them at the time.

The US Federal Aviation Administration is investigating the incident but said all planes are required to dispose of waste at an airport.
