The act or concept of traveling to another continent, and engaging in sexual intercourse with a dead animal
(usually one specific to that region)
"Sam is busy this weekend, he is going on a trip. It probably involves a little intercontinental necrobestiality."
"So I was talking to this guy who does intercontinental necrobestiality..."
"I do work in the field of intercontinental necrobestiality."
It's practicioners fly to foreign countries and fuck dead animals that are indigenous to that region.
For instance go to Australia to fuck a dead kangaroo. Or to Africa to fuck a dead ostrich.
