Hyperspace whiplash was a state that could affect people when they transitioned out of hyperspace.
In the year 9 BBY, Greez Dritus, the Latero pilot, who was on the Stinger Mantis - a luxury yacht - told Cal Kestis, a Jedi Knight, to take a seat prior to their exit from hyperspace so he wouldn't experience hyperspace whiplash.
The phenomenon of hyperspace whiplash was referenced in background conversations within Star Wars Jedi: Survivor, the video game developed by Respawn Entertainment and released in 2023.
