Facebook introduced a handful of new ad units that combine your “Likes,” Facebook Places check ins, and your use of certain apps with advertisements for things like Starbucks, Coke, Levi’s jeans and Budweiser.

In other words, if you happen to click “Like” on the Starbucks page, check into your local faux Italian coffee bar, or use your Starbucks Greek iPhone app, your Facebook avatar could appear in an ad paid for by Starbucks and appearing on your friends’ pages.
