A "BOM" is a what?

Someone in Pakistan came to this blog after using the following search query on Google's Pakistan (.pk) web site:

http://www.google.com.pk/search?hl=en&sa=X &oi=spell&resnum=0&ct=result&cd=1 &q=bom%20making%20book%20in%20urdu&spell=1

The search words were: "bom making book in urdu"

And the link he clicked on was the second one listed, and is titled "how-to-quick-start-guide".

In LDS lingo, "BoM" stands for "Book of Mormon." But I don't think that's what he was looking for.
