An individual who suffers from a condition called strabismus exotropia. Its the opposite of being cross-eyed where one eye looks at you while the other is looking way off to the side.
etymology: the cover of Brave New World that was used in my english class has on it a big picture of a face w/ this condition and under it in bold is written HUXLEY. At the time we didn't know that the author Aldoux Huxley had strabisums exotropia and the picture was likely that of him.
That guy at the back of english class is a huxley.
Which eye do you look at when you talk to a huxley?
