Snu-snu

"Snu Snu" is Amazonian for "sex". Snu Snu is used as a form of judicial corporal punishment for men who illegally set foot on Amazonia.

When men from the Planet Express crew visited the planet in 3001, they were sentenced to death, as required by Amazonian law, through the act of snu-snu, in which the Amazonians continuously raped them. The men were ultimately freed by the Femputer.
