Hella is an American slang term that originated in Oakland, California but has since spread to become native slang to all of the San Francisco Bay Area. It is used as an adverb such as in "hella bad" or "hella good" and was eventually added to the Oxford English Dictionary in 2002. It is possibly a contraction of the phrase "hell of a" or "hell of a lot [of]", in turn reduced to "hell of", though some scholars doubt this etymology since its grammatical usage does not align with those phrases. It often appears in place of the words "really", "a lot", "totally", "very", and in some cases, "yes". Whereas hell of a is generally used with a noun, according to linguist Pamela Munro, hella is primarily used to modify an adjective such as "good".

Cyberspace is a concept describing a widespread interconnected digital technology. "The expression dates back from the first decade of the diffusion of the internet. It refers to the online world as a world 'apart', as distinct from everyday reality. In cyberspace people can hide behind fake identities, as in the famous The New Yorker cartoon." The term entered popular culture from science fiction and the arts but is now used by technology strategists, security professionals, government, military and industry leaders and entrepreneurs to describe the domain of the global technology environment, commonly defined as standing for the global network of interdependent information technology infrastructures, telecommunications networks and computer processing systems. Others consider cyberspace to be just a national environment in which communication over computer networks occurs. The word became popular in the 1990s when the use of the Internet, networking, and digital communication were all growing dramatically; the term cyberspace was able to represent the many new ideas and phenomena that were emerging.
