dummkopf 

Literally, "dumb head," in German. Used often humorously in English, and can be used in the same context as 'dumbass.' It's an insult that, chances are, not many folks will fully understand. Oh well, who cares? It still is a fun word to say!

Me: So, did you take a look at the newest Family Guy episode?

Idiot Friend: Say what?

Me: (Groans) At least I'm not calling you a schweinhund!

Idiot Friend: Lol, you say funny words.
