Here are a few Austrian ones:
“Häferl” (Cup): someone with anger management issues
“Du rüttelst am Watschenbaum” (You are shaking the slap tree): I’m close to deliver the fruit of said tree to you.
“Ohrwaschlkaktus” (Ear cactus): Someone with large, protruding ears
“Saubauch” (Hog belly): A way of telling someone that they are fat and dumb at the same time. But in a nice way.
Finally designers are realizing it’s not 2013 anymore and nobody liked the Win8 designed-in-powerpoint style.
