Something you call someone who thinks they are a
genius, but is too stupid to know how to
actually spell "
genius", and is actually a really dumb person.
That jeanious uses anime for
almost every one of her forum responses, so I called her a "jeanious"; and she thought I was
actually calling her smart! She is so dumb, she doesn't even know how to spell
genius and thought I was giving her props for her forum posts! What a jeanious!
