flatte |ˈfläˌtā| noun : a decaffeinated latte

The construction is similar to “blog” – the last letter of a two-word phrase (“web log”) coupled with the full second word. In this case, “decaf latte” becomes “flatte.”
It's too late in the day for caffeine but I still want a coffee. So, could you get me a flatte if you're going to the cafe?
