From Wikipedia:

 –§–  貴様 — formerly an extremely honorific form of address; in modern speech is as insulting as, but more refined than, "temee"

貴様 is often said (by textbooks) to be the most insulting word used refer to someone, even more insulting than 手前.

Then, what does the article mean when it says that 貴様 is more refined than 手前?

Or is that information just plain wrong?
