Hawking her book.

Funny you should bring that up.

Last semester I took a Mass Communications class and had a paper that the professor took two points off for using hawking instead of hocking. I looked it up and both are correct. I ended up taking my case to the English department chair who informed us we were both incorrect because it was slang no matter which you used.

Only to an English department chair. LOL!

According to my dictionary (Oxford):

Hock²
Informal term for pawn.

Hawk²
carry around and offer goods for slae, typically advertising them by shouting.

In case anyone cares. ;-) There isn't any selling definitely for "hock", and no pawning definition for "hock".
