(slang) A foolish or stupid person.
The definition of a jughead is slang for a foolish or stupid person.
A person who drives a car without insurance is an example of a jughead.
An Internet browser similar in operation to Veronica, but limited to keyword searches in directory titles on a specific site in Gopherspace. Jughead indexes the keywords in directory titles, but does not index the files within the directories. Playing off Archie and Gopher, subsequent developers of search mechanisms tried to stay with the Archie comic book/rodent theme, proving once and for all that even acronyms can be fun. Unfortunately, there is not even a hint of humor reflected in the chosen names of more recent and more powerful browsers. See also Archie, browser, Gopher, Gopherspace, Internet, and Veronica.
An Internet utility used to search for a keyword throughout all levels of a Gopher menu. With Jughead, you do not have to jump from one menu level to the next.
