Not an ass guy? All good 'cause Fetish Friday is here to celebrate girls that have butts like Marisa Miller's abs—flat as a washboard! Sure, we usually love thicky-thick chicks with thumpers, but there's something to be said about the less-endowed. The entire modeling industry probably wouldn't exist if there wasn't a market for ass-less beauties. Besides, onions can make you cry, but pancakes are a great sight in the morning.

So turn off that Sir Mix-A-Lot and get ready to jam to track 10 on the new Clipse album—because like Pusha-T says: "I used to be all about a fat ass, then I found a cutie with a flat ass." If our list of voluptuous video vixens didn't do it for you, then check out our list of the 10 hottest celebrities with small bums...
