Fat Shakes are a parody of Hostess Twinkies Milk Shakes. From the creators of Fat Cakes, fat shakes are milkshakes made from Fat Cakes. Sam really loves them. In iStart a Fanwar, Sam drinks a fat shake, and is obsessed over them. It is possible she drank more than one due to a goof. She said it is like "sucking Heaven through a straw."
