“Is ‘ginormous’ a real word now? Ugh.”
Was mainstreamed in the movie Elf. There really is no final authority when it comes to determining which words become part of a particular language.
That’s true. Slang usage in literature just chafes me. That’s all. Maybe the word is no longer slang. Certainly published articles using it will help it along! Of course, I still get irritated by the fact that we can’t be bothered to use the word “cacti” as the plural of cactus.
