A lonius is someone who is both an introvert and an extrovert and neither one is more dominant than the other. Thus an individual with an internal conflict and often finds themself being both a loner and genius at the same time.
Have you met the new girl yet? She is such a lonius- always the first to go home from a party but loves being the center of attention. I also hear she's a total genius.
