Well, honestly any word is a ''real'' word if it's given meaning. After all, all words we use everyday and whatnot are made up.
Humans didn't have everything embedded into their brains from the start, they made up their own languages, gave their words meaning, etc. If I recall correctly if a word is pretty commonly known, as well as it's intended meaning, it ends up being added to the dictionary.
I don't think you're ready for this jelly~
