In 2364, Geordi La Forge attempted to tell a joke to Data, involving a person staggering as he walks up to a girl. The punchline of that joke was "just try that in hyperspace!" (TNG: "Conspiracy")
In theoretical physics, hyperspace refers to a hypothetical higher-dimensional space in which our universe, and possibly others, exist. It has been popularized as a subspace-like dimension in various Isaac Asimov stories, Larry Niven's "Known Space" series, and in the Star Wars film series.
