For whatever it is worth. Girlfriend received a 10 year Tourist Visa in February. We played everything by the numbers. We shared paying for the airline ticket to US and noted such on visa application. DID NOT BUY TICKET until after receiving the visa, per US Embassy and application advisory. Do not, I repeat do not BS these people. They are not stupid and they have heard every story in the book. If a false statement is discovered, you have bought the farm and have no recourse. I would suggest your friend note the relationship as FRIEND on the application. You may be lovers and plan on getting married someday, however you are indeed friends too. If you have any other agenda other than a visit to meet your parents, forget the tourist visa. Also, as pointed out, the visa does not guarantee entry. I sweated bullets waiting for her to clear immigration, but it all worked out.
