The Ultimate Hitchhikers' Guide to the Galaxy里面讲hitchhikers之间是有俚语的:
比如“Hey, you sass that hoopy Ford Prefect? There's a frood who really knows where his towel is. ”
Sass: know, be aware of, meet, have sex with;
hoopy: really together guy;
frood really amazingly together guy.
并且就和Harry Potter里面的“麻瓜”对应,道格拉斯·亚当姆斯也有一个词用来形容nonhitchhikers——strag。
