In 2010, an online petition created by the University of California, Davis to declare "hella-" the official SI prefix for 10^27, also known as 1,000,000,000,000,000,000,000,000,000 or one octillion, gained over 60,000 signatures. Let's be honest: the only time when we talk about the upper prefixes (exa-, zetta-, and yotta-) is when we are talking about data storage. No, seriously. That is the only time we use exa-, zetta-, and yotta-. And 99% of the time, we use those terms over the Internet.
The term "hella" is slang for "hell of a," et al. Last I checked, 10^27 is a hell of a lot of almost anything. If we officially recognized Internet slang as a unit prefix that we know will not be used offline, wouldn't that make 'hella' sense?
