wisenheimer

Meaning

Noun

• A self-assertive and arrogant person; a know-it-all or smart aleck.

Origin

• First used in the early From wise + the German demonymic ending -enheimer.
• The form might be an alteration of the similarly formed and synonymous Schlauberger (19th c.), possibly influenced by Pappenheimer and/or involving a pun on Waisenheim. On the other hand, the surname Weisenheimer actually exists, both in Germany and the US. It goes back to the towns of Weisenheim am Berg and Weisenheim am Sand (both in Palatinate).
