Backpfeifengesicht
Etymology
German, joining "Backpfeife" ("a slap to the cheek," from "Backe," cheek, plus a colloquial use of "pfeifen," to whistle) with "Gesicht" ("face") — literally a "slap-face." It is jocular rather than genuinely violent. Its cartoonish specificity is exactly why untranslatable-word lists love it.
noun · /BAHK-pfy-fen-guh-zikht/
A face that looks like it deserves to be slapped.
What it names
The comic sense that someone’s smug expression is practically asking for a smack.
Example
The politician’s permanent smirk was a textbook backpfeifengesicht.
Related idea
Unlike an insult about character, it targets only the impression a face gives — closer to punchable than to any moral judgment.
