Having sex.

Origin: In the science-fiction works of Frank Herbert's "Dune," space travel was accomplished by the usage of psychotropic drugs. In a similar fashion, sexual intercourse releases brain stimulating chemicals like dopamine and thus also achieves a transcendent state.

Sex if often played up by statements refering to travel like "I will send you around the world." It's only nature that the two should be combined in sci-fi geek slang.
