If you saw it, there was a poll for the definition of xyster. The answers were a South American Monkey, The point of time between being a star and being a black hole, The last name of a European sientist and a surgery tool. One person said it was a black hole and one person said it was a surgery tool. Surgery tool is correct!

I also asked how to pronounce xyster. The options were zister, wister, wistar and zisty. One person said zister and one said zisty. Zister is the correct pronunciation.
