A fear of crowds is called enochlophobia, and it is safe to say the video above is likely to provoke a strong reaction from anyone who has it.
The clip from China shows hundreds of swimmers in bright inflatable rubber rings squashed together.
Hardly any water can be seen in the melee at the Heiyuhu Water Amusement Park in the city of Daqing.
According to Newsflare, an employee of the water park told local television that scenes like this were common during weekends and holidays.
* Porsche actually built an inflatable swan 911
* Thousands of people crammed into one pool to escape a heatwave in China
The video was posted onto the TikTok channel of Vice News and has been viewed more than 500,000 times.
Commentators were pretty horrified by the thought of sharing a pool with so many other people.
”At this point are you swimming in water or are you swimming in people?” asked one.
Many compared it to a bowl of Froot Loops cereal.
“I’ve always wondered what hell actually looks like,” was another of the more than 5000 comments.
Not all were negative, however: “Love it. Wish I was there. Looks like such a great time.”
