I used this word in the context of the movie. Kirk Lazarus (Robert Downey Jr.) is explaining to Tugg Speedsman (Ben Stiller) why you should not go full retard when taking a film role. Imo, Germany's nowadays actions are very questionable. I put Germany into Tugg's shoes. That's all.It's the use of the specific word, which in modern English vernacular, is used primarily to insult people who aren't of normal mental capacities.
