Roadtrip remnants are basically the trash left lying in your car after concluding a long roadtrip, usually with a few friends in tow. They usually consist of, but are not necessarily limited to, (half) empty bags of potato chips, food crumbs, empty soda cans/bottles, food wrappers, fast-food drink cups, and maybe a condom or two.

(noun) A successful type of theft which results in an acceptable, impressive and rewarding payday for the protagonist.
