Overflow Jump
The most complex type of "jump" in the world record TAS speedrun for Super Mario 64. It's where you go SO UNBELIEVABLY fast that you move through something called "parallel universes". You move through MULTIPLE of them, then rotate your camera, and then jump. This allows you to move through a parallel universe vertically. Then it kicks you out because of reasons I'm not gonna talk about, and boom! You just did an overflow jump!
"What is this mess? Parallel universes? Quartersteps? Overflow jumps are weird."
