Chounyuu is a website created by [[1]] to serve as a community for people who like giant breasts at a time when Gelbooru was deleting art of breasts above a certain size.<ref group:"References">https://discordapp.com/channels/191608193833631753/191608193833631753/195013754176536576</ref> It launched at precisely 2011-07-18T21:37:06Z<ref group:"References">https://discordapp.com/channels/191608193833631753/191608193833631753/387706000884629504</ref> The website’s name comes from the Japanese term “超乳” or “Ultra Milk.” It essentially means very large breasts; the biggest size there is. In general this implies each breast is much larger than the head.

Imageboards
The Chounyuu imageboard is also home to “[[6]]” art since it doesn't warrant having its own board. Cheekily, Tea opened the Ultrabutts channel on the 31st of March 2018, and while users joked that it would be closed by the 2nd of April, the channel has persisted.
